Notebook and process for production thereof

A notebook including a group of a preset number of consecutive unit forms which are printed on both faces thereof and spreadably zigzag-folded is produced through a process that includes: printing on both surfaces of a continuous web by two printers each equipped with an endless belt-shaped printing plate, with intermediate inversion of the two surfaces of the web, followed by zig-zag folding and cutting and separating the printed web for each of the preset number of forms. The obtained notebook is capable of preventing falsification and missing pages by inclusion of a horizontal ruled line provided in a main data region and formed of a succession of micro characters.

TECHNICAL FIELD

The present invention relates to a high-security notebook which is prepared by zigzag folding a continuous form having prints on both sides and provided with capability of preventing falsification and missing pages, and a process for producing the notebook.

BACKGROUND ART

The present inventor developed a fundamental printing technology of using an endless belt-shaped printing plate for manufacturing an elongated strip-shaped printed continuous form by printing on an elongated continuous web form (continuous paper web). The technology of printing on a continuous form using an endless belt-shaped printing plate is applied to preparation of booklet forms for payment of a pension and insurance or a tax, a calendar, a contract, an operation manual, and books, etc.

Moreover, it is widely used also for preparation of individual or separate sheet prints requiring high quality and high security, such as a service ticket, a travel ticket, a gift certificate, a cash voucher, a stock certificate, and a debenture from a feed roll of continuous web form along with a progress of printing technology in recent years.

By the way, a notebook has been conventionally prepared by covering a plurality, e.g., 40 or 60, of inside paper sheets, with a front cover and a back cover, and by fixing or gluing the sides of the sheets to form a booklet. The inside paper sheets of a notebook are formed by printing ruled lines on each face of paper sheet. Although the ruled lines are formed as solid lines or dotted lines, the inside paper sheets of a notebook are formed of separate sheets.

In the conventional technology of printing on a continuous web form taken out from a paper feed roll using an endless belt-shaped printing plate, printing is performed on one side of a continuous form and not on both sides of the continuous form continuously. Accordingly, no technology has been developed for printing continuously on both sides of a continuous form, or for folding-up zigzag such an elongated continuous web form printed on both sides thereof to prepare a notebook.

In a conventional notebook, individual paper sheets are stacked to form a booklet of inside paper sheets, which is then covered with a front cover and a back cover. For such a notebook prepared from paper sheets, it is difficult to find an inferior product caused by possible lack, missing or damage of a portion of inside paper sheets, or to notice such a lack of page on a part of inside paper sheets.

On the other hand, the replication technology by a copying machine is developed in recent years and, in connection therewith, it is desired to develop a high-security print of which reproduction is impossible with a copying machine. Similarly, it is also expected to develop a notebook of which reproduction of contents such as characters is difficult. However, a conventional notebook is not provided with capability of preventing the falsification or omission of inside paper sheets between a front cover and a back cover, and it has not become a high-security one.

SUMMARY OF THE INVENTION

The present invention has been made in consideration of the situation mentioned above, and an object of the present invention is to provide a notebook which has been prepared by folding zigzag a continuous web form printed on both surfaces thereof and is provided with capability of preventing the falsification or omission of pages to satisfy a high-security, and a process for production thereof.

Another object of the present invention is to provide a notebook which has been prepared by folding zigzag a continuous web form into a form allowing spread-reading and is therefore different in type from a conventional notebook in a form of booklet formed by firm binding of inside paper sheets.

According to the present invention, there is provided a notebook, comprising: a unit form group including a preset number of consecutive unit forms zigzag-folded and printed on both faces thereof, said unit form group having been prepared by providing a continuous web form which has been printed on both surfaces thereof including at least one surface on which the unit forms are printed, folding up zigzag the continuous web form for every unit form, cutting the continuous web form for every preset number of consecutive unit forms, and stacking the unit forms to prepare a notebook, so as to allow spread-reading of the respective unit forms,

wherein each unit form has a note face, and the note face includes a main data area equipped with a plurality of printed ruled lines, a date region, and also a succession of micro characters printed on at least one part thereof.

In a preferred embodiment, the printed ruled lines in the main data area include horizontal ruled lines formed with a succession of micro characters.

The present invention also provides a notebook, wherein the group of unit forms spreadably zigzag-folded and stacked of the above-mentioned notebook are covered spreadably with a book cover including a front cover, a spine and a back cover, and is disposed spreadably, wherein

the front cover and the back cover are each provided with a cover plate applied onto a back thereof so as to allow insertion of a sheet behind the cover plate from an inward position of the cover plate,

a first unit form and a second unit form are held in a folded state by insertion between the back of the front cover and the cover plate, and

a last unit form and a last but one unit form are held in a folded state by insertion between the back of the back cover and the cover plate.

The present invention also provides a process for producing a notebook, comprising:

successively printing a multiplicity of unit forms including ruled lines formed of a succession of micro characters by a first printer equipped with an endless belt-shaped printing plate on one surface of a continuous web form supplied from a feed roll,

inverting the front and back surfaces of the continuous web form with a form inverter,

printing on the other surface of the continuous web form by a second printer equipped with an endless belt-shaped printing plate to provide the continuous web form with prints on both surfaces,

folding up zigzag the continuous web form for every unit form to pile up the zigzag-folded continuous web form on a stack, and

cutting and separating the continuous web form for every preset number of consecutive unit forms, thereby providing a notebook including a group of the preset number of consecutive unit forms which have been printed on both faces thereof and spreadably zigzag-folded.

According to the present invention, a continuous web form which has been printed on both faces thereof is zigzag-folded for every unit form and piled up, and the zigzag-folded web form is cut and separated in a width direction for every preset number of unit forms to form a zigzag-folded notebook. The notebook is formed not of separate sheets but of respective unit forms (inside paper, successively connected with each other, so that falling-off of unit forms can be prevented and the breakage or damage of the contents can be securely confirmed in case where it occurred.

Moreover, the note face of each of the unit forms constituting the notebook is printed with a succession of micro characters (used herein to mean characters, numerals or symbols which are at most 1 point (=0.3514 mm) in size and cannot be recognized at least by observation with naked eyes to convey some meaningful data). Micro characters are collapsed when copied by using an ordinary copying machine, such as an electrophotography copying machine, so that the reproduction thereof is impossible, and the notebook is provided with a falsification prevention function to ensure a high security. A succession or row of micro characters are preferably incorporated as at least a portion of a horizontal ruled line on a note face.

Furthermore, the notebook can be read in a spread state, allows checking of data recorded thereon in a larger area at one time and is thus a new type of notebook.

EMBODIMENTS OF THE INVENTION

Hereinafter, some embodiments of the present invention will be described with reference to accompanying drawings.

First Embodiment

FIG. 1is a configuration diagram for illustrating an operation principle of an embodiment of notebook manufacturing apparatus, whereby an elongated continuous web form (continuous paper) is successively printed on both surfaces thereof by means of a plurality of printers, that is, at least two printers, each equipped with an elongated, flexible, endless belt-shaped printing plate; and the continuous web form is zigzag-folded up to form a group of zigzag-folded unit forms.

A notebook manufacturing apparatus10may be referred to as a rotary press printing machine whereby an elongated continuous web form (continuous paper, rolled paper)12supplied from a feed roll11is successively printed by elongated endless belt-shaped printing plates13.

As shown inFIG. 2, the continuous web form12fed out of the feed roll11is provided with punched holes16at an equal pitch of e.g. ½ inch intervals along marginal zones15on both sides by a perforation apparatus (not shown). The punched holes16are formed as guide holes, whereby the continuous web form12is exactly guided and sent in the longitudinal direction thereof. Thus, the continuous web form12sent out from the feed roll11is sent to the first printer18through the guide roller17, and is suitably printed on one of its front and back surfaces, e.g. back surface, by a first printer18. The continuous web form12is then sent to a second printer19, whereby the continuous web form12is printed with watermarks. The continuous web form12printed by the second printer19is sent to a form inverter device20, whereby the front and back surfaces of the web form12are turned upside down. The reversed continuous web form12is then sent to a third printer21for printing on the other surface, e.g., the front surface. The printers18,19and21each have an identical structure and identical function, and are used for respectively predetermined printings.

The endless belt-shaped printing plate13of the printers18,19, and21is produced from a flexible elongated resinous relief printing plate disclosed in JP2011-53424A and JP2012-96490A (the disclosures of which are incorporated herein by reference). A plurality of the thus-produced resinous relief printing plates are connected one by one in a longitudinal direction, and then both longitudinal ends of the connected printing plates are connected to form an endless belt-shaped printing plate13. The endless belt-shaped printing plates13are produced by connecting the resinous relief printing plates at an installation site of the respective printers18,19and21, and are twisted around the respective printers18,19, and21.

The endless belt-shaped printing plates13are each formed of a flexible film-like resinous relief printing plate, and the respective endless belt-shaped printing plate13(13a,13b,13c) are each wound about a plate cylinder23and a guide cylinder (guide roller)24and are operated synchronously. More specifically, each endless belt-shaped printing plate13(13a,13b, or13c) may have a longitudinal and circumferential length appropriately selected from a range of several meters to several tens of meters, for example, 7 m-50 m. The endless belt-shaped printing plates13a,13band13c(13) have identical longitudinal lengths, and operated synchronously.

The endless belt-shaped printing plate13awound about the plate cylinder23of the first printer18is equipped with, for example a pair of inking rollers25a, to which a printing ink of predetermined color, such as black, blue or green, is supplied. The supplied printing ink is applied to the plate surface of the endless belt-shaped printing plate13a. The printing ink applied to the plate side of the printing plate13ais transferred for printing to the continuous web form12supplied from the feed roll11. The continuous web form12is pressed by an impression cylinder26, and the image on the endless belt-shaped printing plate13ais printed to the continuous web form12by the pressure.

In the first printer18, note faces (page faces) of unit forms12a,12b, . . . , as shown inFIG. 2, are formed by printing on the front surface or back surface of the continuous web form12. Necessary information or a required data description column is formed on the note face of each unit form12a,12b, . . . .

More specifically, in case of using the notebook manufacturing apparatus10for manufacturing a notebook for use as a research-and-development note or a technical development note, each note face may be provided with a main data area27for indicating a progress of research or technical development, a study subject, contents of various actions, a memo, etc., and also a date column28for indicating year, month and day of record, an attestation (or acknowledgement) column29for superiors, a name column30for indicating the name of a person in charge and a participant, etc.

The main data area27includes horizontal ruled lines31and vertical ruled lines32to form a note area, wherein successive row numbers are attached to rows between successive horizontal ruled lines31, and successive page numbers are allotted to an upper corner or a lower end center of the respective note faces (page faces) of consecutive unit forms12a,12b, . . . , of the continuous web form12. Each horizontal ruled line31, except for the lowermost one, may be formed as a horizontal ruled line formed of a succession of relatively fine micro characters of 0.3P (point)-0.7P (point). Some example of the horizontal ruled line31is described later.

After the page faces (note faces) of the unit forms12a,12b, . . . , are consecutively printed on one surface (form surface) of the continuous web form12, the continuous web form12is guided to a second printer19, where watermarks33of the shape of, e.g., a cherry petal, are printed on the respective note faces (page faces) of the unit forms12a,12b, . . . , of the continuous web form12by inking rollers25band an endless belt-shaped printing plate13bof the second printer19. Such watermarks33may be attached in order to express a looking of high-class printing and may also be given as other shapes than petals, or a mark or name of a company, etc.

After the page faces (note faces) of the unit forms12a,12b, . . . , are printed by the first printer18and the watermarks33are printed on the note faces by the second printer19at a note face, the continuous web form12is sent to the form inverter (or turnover) device20where the back and front surfaces of the continuous web form12are reversed.

The form inverter20may be composed as shown inFIG. 3, and the continuous web form12conveyed thereto is guided to a lower guide bar35inclined 45 degrees to the run direction so that the non-printed (e.g., front) surface of the web form12contacts the bar35, further guided toward a lateral side and then inverted upside down by a rotatably disposed guide bar36. At the guide bar35, the web form12is guided upwards and then turned over. The reversed continuous web form12is led to an upper guide bar37, where its run direction is changed so as to intersect perpendicularly with the previous one. The upper guide bar37crosses so as to intersect perpendicularly to the downward guide bar35as viewed in plane, and the continuous web form12is further turned upside down to be guide to a third printer21.

In the third printer21, printing is continuously performed to the front (or back) surface of the continuous web form12similarly as in the first and the second printers18and19using an endless belt-shaped printing plate13cand the inking rollers25c. In a specific example, by the third printer21, the same printing as the first printer13is performed to the front (or back) surface of the continuous web form12. Therefore, a series of printings can be continuously performed to the front and back surfaces of the continuous web form12by the first printer18and the third printer21.

After the printing on both surfaces is performed, the continuous web form12is led to the inspection device40, where the continuous web form12is inspected with respect to a positional deviation, printing unevenness, etc. The inspected continuous web form12is then guided to a cutting machine41, where marginal zones15of the continuous web form12are cut off along slitter lines15a(FIG. 2). It is also possible that the cutting-off of the marginal zones15of the continuous web form12with the cutting machine41is omitted, in case where the continuous web form12after the inspection needs to be processed by a computer etc. In this case, the continuous web form12may be caused to bypass the cutting machine41and be directly sent to the zigzag folding apparatus44.

As the zigzag folding apparatus44, a zigzag folding apparatus equipped with a fold line generator as disclosed in JP5324950B (incorporated herein by reference) may be used for example. According to such a zigzag folding apparatus, the continuous web form12is alternately provided with a ridge-like projection line or a valley-like depression line (each functioning as a fold line) in transverse directions for every unit form12a,12b, . . . . The zigzag folding apparatus44is equipped with such a fold line generator and a press for fixing the resultant fold lines, so that the continuous web form12is provided with a zigzag-folded state for every unit form12a,12b- - - .

Moreover, the continuous web form12has been printed on both surfaces thereof by the first to the third printers18,19and21, so that there is provided with a continuous web form including consecutive unit forms printed on both surfaces and zigzag-folded with alternate ridge-like projection lines and valley-like depression lines extending in transverse directions. Thus, by the zigzag folding apparatus44, the continuous web form12is zigzag-folded for every unit form12a,12b, . . . , and is successively conveyed to and piled up on a stacker45.

The continuous web form12folded up in a zigzag shape on the stacker45is caused to form a group46of preset number, e.g., 50 or more, of unit forms12a,12b, . . . , and one volume of notebook may be obtained by cutting off such a unit form group in the transverse direction and separating it from the remainder of the continuous web form12. If desired, such a continuation of zigzag-folded continuous web form12may be provided with plural volumes, e.g. two volumes of printed notebook data to form two groups46of unit forms, which are then cut in separation for each group to provide plural volumes of notebook.

An example of notebook50consisting of a zigzag-folded unit form group46is shown inFIG. 4. The notebook50consists of a unit form group comprising 54 sheets of unit forms which has been cut out from a zigzag-folded the continuous web form12and piled up. The unit form group constituting the notebook50in this example has 54 note faces (page faces) including sequentially a unit form A, a unit form B, a unit form1, - - - , a unit form50and a unit form Y, and a unit form Z on a front surface (one surface) of the continuous web form12. Also on the back (on the other surface) of the continuous web form12, a unit form Z, a unit form Y, a unit form50, - - - , a unit form1, a unit form B and a unit form A are sequentially formed corresponding to the front surface.

The notebook50consisting of the unit form group46may be formed of unit forms of A4 size or B5 size, for example, and the first unit form A on the front surface side may constitute a front cover page, and the last unit form Z on the front surface side may constitute a back cover. The second unit form B on the front surface side can form a printed contents page for example. Accordingly, one notebook50consisting of a single unit form group46may include at least 50 inner paper sheets giving at least 50 pages of unit form1, unit form2, - - - , unit form50on each of the front and back surface sides and totally at least 100 pages on both surface sides. It is also possible that one zigzag-folded notebook including a plurality of unit form groups without separation constitutes a notebook having plural times of volume as that of a notebook50comprising a single unit form group.

Anyway, the zigzag-folded notebook50allows spread-reading of reading and checking data described on the notebook in a spread state and therefore in a wider area, thus giving a better scrutinizing efficiency.

By the way, a notebook50of a unit form group can be modified by bonding a thick paper for a cover onto each of unit form A and unit form Z on the front surface side of the continuous web form12to provide a zigzag-folded notebook with a front and back cover pages. Such a zigzag-folded notebook of so-called “houchouori” is suitable for spread-reading of a supra, the Bible, a long speech manuscript, etc.

Moreover, in one notebook or a plurality of notebooks, each of unit forms12a,12b, . . . connected in succession in a zigzag-folded state for constituting a notebook50may have a note face made up as shown inFIG. 5. More specifically, a unit form12amay have a note face including a main data area27, a date column28, an attestation column29, a name column30, a successive page number47, successive row numbers48, an index column49, and further an optional description column (not shown).

The index columns49are provided, e.g. as solid printed images at side edges of unit forms12a,12b, . . . , and a common index is given to an identical row of a group of e.g. 10 successive unit forms, such as unit form1to unit form10, unit form11to unit form20, unit form21to unit form30, unit form31to unit form40, or unit form41to unit form50.

Moreover, the indexes49may alternatively be given as outlined characters in a colored background instead of printed solid images at side edges of unit form1-unit form50. Examples of such outlined characters may for example include names of administrative units, such as states, or names of tourist sites in administrative units on respective unit forms1to50. In that case, supplemental indications regarding the administration unit names or tourist site names, such as names of broader administrative units or country name, may be given as solid printed images on e.g. unit forms48to50. In this case, the row number of the index may be subtracted by a number of corresponding pages. As result, the breakage or omission of any unit forms can be easily found by observation of the index columns.

By the way, the main data area27of the unit forms12a,12b, . . . , may for example be formed by a multiplicity (e.g. 25) of horizontal ruled lines31and a vertical ruled line32, for example. Among these, the horizontal ruled lines31for example may be formed of a succession of relatively fine micro characters. In an example, the uppermost and lowermost horizontal ruled lines among the horizontal ruled lines31may be formed of micro characters of 0.7P (point)-1.0P (point), and the remaining horizontal ruled lines31may be formed of finer micro characters of 0.3P-0.6P. Fine micro characters forming the horizontal ruled line31are difficult to recognize the contents thereof with naked eyes. In case of being copied with an electro-photo graphic copying machine, the micro characters forming the horizontal ruled lines31will be collapsed, and reproduction of the characters is impossible, thus preventing falsification to realize a high security.

Moreover, the lowermost horizontal ruled line31may be formed of micro characters, of which the sizes are gradually enlarged from an intermediate point toward the end-of-the-line. It is also possible that the end of the lowermost horizontal ruled line31are formed of characters of e.g. 3P (size of about 1 mm), which can be recognized by naked eyes.FIG. 6Ashows an enlarged view of a part A (a terminal point of the lowermost line31) inFIG. 5, andFIG. 6Bshows an enlarged view of a Part B (an intermediate point of the remaining horizontal ruled lines31) inFIG. 5at which the contents of micro characters can be recognized only after enlargement through a magnifying glass. As shown inFIGS. 6A and 6B, the micro characters forming the horizontal ruled lines31represent a corporate logo of the applicant company “MISATO MIRAI 21” as an example of successive micro characters forming a ruled line. Thus, the horizontal ruled lines31printed in the main data area27of the unit forms12a,12b, . . . , in this embodiment are not mere ruled lines but those formed of micro characters which imparts an identification function to the ruled line itself.

Moreover, the lowermost horizontal ruled line31may also be formed as a horizontal ruled line of characters of which the sizes are decreased from the starting end to an intermediate point. Anyway, it is desirable from a discernment function that the lowermost horizontal ruled line31in the main data area27is formed of characters, a part of which is enlarged in size.

Alternatively, it is also possible that the uppermost and lowermost horizontal ruled lines31of micro characters of identical sizes as the other horizontal ruled lines.

In the above, there has been described an embodiment of using endless belt-shaped printing plates13(13a,13c) of the first printer18and the third printer21for printing on back (or front) surface and front (or back) surface, respectively, of the continuous web form12, zigzag-folding up the thus-printed continuous web form12by a zigzag-folder44to form a group of a preset number of successive unit forms46, and cutting the continuous web form12for every one or plural groups of successive unit forms to produce a notebook50comprising one or plural groups of zigzag-folded unit forms.

In the above-described embodiment, the front and back surfaces of the continuous web form12may be printed with inks of identical colors or different colors. However, it is impossible to change the color of ink for printing the respective unit forms12a,12b, . . . on the back (or front) surface of the continuous web form12from an intermediate point, or perform a multi-color printing. It is however possible to change the color of ink for printing on the back (or front) surface of the continuous web form12from an intermediate point, or perform a multi-color printing, if a number of printers corresponding to a number of ink colors required for printing on one (i.e. front or back) surface of the continuous web form12are used and they are operated according to an appropriate schedule of operation.

Second Embodiment

A second embodiment of the present invention will be described with reference toFIG. 7toFIG. 10.

The second embodiment is obtained by covering a notebook50produced by the notebook manufacturing apparatus10according to the above-mentioned first embodiment with a book cover60. The book cover60is formed as a makeup cover made of a resin, a skin, a pasteboard, a wood, etc., as shown inFIG. 7andFIG. 8. The book cover60may be prepared by bend and fold-up a sheet material into a succession of a front cover61, a spine63and a back cover62which are closable and spreadable for reading the contents. On the face of the front cover61of the book cover60, a column for inserting a title and an owner's name of the notebook (FIGS. 7 and 8), if needed.

Moreover, as shown inFIG. 9illustrating where the book cover60in a spread and opened state, a cover plate61, of e.g. a plastic sheet, is applied or fixed along three peripheral sides on the back of the front cover61except for the boundary (an inner open side) with the back of the spine63. The cover plate66on the back of the front cover61is equipped with a pocket67for inserting and holding separate paper sheets and the like and, at lower parts thereof, is further equipped with a holder pocket67for holding name cards, etc. and a holder pocket68for holding cards and the like.

Furthermore, in the spread state of the book cover60(as shown inFIG. 9), a portion of the unit forms constituting the notebook50is inserted from the opening (inner side opening) on the boundary with the back of the spine63of the cover plate66and held therein. More specifically, the unit form A and the unit form B on the front surface side of the notebook50are folded together and inserted from the inner side opening of the cover plate66and held thereat. Moreover, a cover plate71is applied like the cover plate66to the back of the back cover62of the book cover60, and the unit form Y and unit form Z on the front surface side of the notebook50are folded together and inserted from an inner side opening of the cover plate71, and held thereat. As a result, the notebook50is wholly covered, stored and protected with the book cover60.

When the book cover60storing the notebook50is conveyed or spread open, as the notebook50is not in a form of booklet prepared by firm binding but has been prepared by zigzag folding-up, the inside papers forming folded unit forms of the notebook50can be freely spread and not constrained about intermediate spreading or falling. In this second embodiment, in order to hold the notebook50stably in the book cover60, stoppers72and73are provided on the base sides of the front cover61and the back cover62, so that non-intentional spreading or falling of intermediate unit forms of the notebook50is prevented. The stoppers72and73may be disposed at at least one part on the base sides of the front cover61and the back cover62, respectively.

Although an embodiment of disposing stoppers72and73on the base sides of the book cover60is explained above, the stoppers72and73can also be disposed on both top and base sides.

Other Embodiments

In the above, embodiments of the present invention suitable for using a notebook50as a research-and-development note or a technical development note have been mainly described, but such a notebook50is also utilizable for use as a risk management note or an information control note.

An example of such a risk management has been proposed to have a note face of each unit form including columns for fill in necessary data for personal arrangement or self-control, such as various assets, liabilities, illness, and care, information for the life of every day, etc. Details of contents therein may be available in, e.g., “moshimo note” (roughly meaning a provident note)”, written by Michiko Susai, published from Life and Ending Center (a non-profit organization) (2004).

Moreover, as an example of an information control note, it may be possible to refer to “EVER NOTE”, written by Shinya Kita, published from K.K. Gijutsu Hyouron-sha (2011), which has proposed a note face of each unit form including an information arrangement column for collecting information of concern, an information processing column, an information check column, an information application column, etc.

Furthermore, while there has been described an embodiment wherein a notebook manufacturing apparatus is used to successively produce one or plural group(s) of unit forms successively from a continuous web form, it is also possible to use a type of notebook manufacturing apparatus using a wide endless belt-shaped printing plate for printing on a continuous web form having a large width to produce plural (e.g. two) groups of unit forms in parallel.

Moreover, in the above-described first embodiment, there has been described an embodiment wherein, in the printing on both surfaces of a continuous web form by using a first printer18and a third printer21(i.e., except for a second printer19for printing watermarks), an essentially identical pattern of printing (except for a possible change in order of printing on unit forms) is performed on both surfaces. It is however not essential that the contents of printing on both surfaces of the continuous web form performed using the first printer18and the third printer21are identical. Particularly, it is possible to restrict the printing of ruled lines formed of a succession of micro characters to only one of both surfaces and perform a simple printing, such as printing of only management data and without including micro characters, on the other surface.
