Title: Collinear printing method with page-type upfront gold-stamping, matting and snowflake printed patterns, and printed product thereof

Description:
BACKGROUND OF THE INVENTION 
     1. Fields of the Invention 
     The present invention relates to a collinear printing method with page-type upfront gold-stamping, matting and snowflake printed patterns, and a printed product thereof, and more particularly to the method applied to an advanced page-type printing machine and a novel printing process in a same-line operation to complete the required special stamping and printing effects, so as to improve the printing efficiency and save the total printing cost. 
     2. Description of the Related Art 
     In the printing industry, the so-called “gold-stamping” technology refers to the technology of processing a “printed matter” by a color printing process, and then attaching a metal foil material onto a part of the printed matter. Since the foil material is generally a gold, silver or red color material with brilliant brightness, and the transfer process is completed by a hot press mounting technology, so that such technology is generally called “Gilt”, and the printed matters of this sort are commonly used in wedding cards, greeting cards, exquisite business cards, and hardcover publications. 
     In a traditional manufacturing process, the “gold-stamping” process is an off-line operation. In other words, after the printed matter is processed by the color printing process in a printing machine, a semi-finished good is sent to a designated “blancher” for a secondary manufacture, and then a finished good of the printed matter is manufactured. Obviously, such off-line manufacturing process is time-consuming, thus incurring a higher printing cost and resulting in a higher price of the printed product. 
     In addition, the so-called ground snowflake printed pattern refers to a special printed pattern formed by printing a repulsive paint and a gold paint which are mixed with each other in a certain ratio on a part or the whole of an end surface of a printed matter, and a layer of rough particles and a special protruding printed pattern are added to increase the feature of the printing layout and the texture of the printed product, and the different effect between the ground and snowflake patterns resides on that the gold paint comes with different particle sizes to provide different visual images. In other words, the particles of a frosted ink are large and rough, but the particles of the snowflake ink are small and fine. 
     At present, the method of printing the products of this sort generally adopts a four-color automatic printing machine to print desired colors and patterns onto a printed matter and then send the printed matter to another printing machine in an offline operation to coat a special frosted ink or snowflake ink, so as to complete the whole printing process. 
     The conventional printing process seems to be reasonable, feasible, common, and capable of achieving the required printing effect, but the complicated operation process including loading, unloading and moving the printed matter in the offline operation decreases the printing speed and efficiency significantly and fails to meet the cost-effective and efficient requirements. Obviously, the conventional process requires further improvements. 
     SUMMARY OF THE INVENTION 
     Therefore, it is a primary object of the present invention to use a single printing process to print expected gilt, colored and frost-like or snowflake printed patterns, so as to achieve the effects of improving the printing efficiency and saving the printing time and cost. 
     According to the invention, a page-type seven-color automatic printing machine is used, an adhesive glue is filled into a first printing ink set, and a second printing ink set is modified to be a cold stamping device. A drum-shaped foil material is installed, and each printing ink set at the middle section is filled with each color printing ink according to printing requirements. The last printing ink set is filled with a repulsive paint and a gold paint, and printing and delivery process are carried out. The first printing ink set coats an appropriate amount of the adhesive glue partially onto a printed matter according to a soft printing board pattern, and then a corresponding stamping press board of the second printing ink set attaches the foil material with the corresponding pattern onto the printed matter by a laminating adhesion method to complete an upfront partial cold stamping operation. Each printing ink set disposed at the middle section completes each color printing operation in a same-line procedure, and the last printing ink set coats a repulsive paint and gold paint onto the printed matter to complete the same-line printing operation of printing the round or snowflake-like printed pattern onto the printed matter according to the mesh size of a mesh ink roller of the gold paint.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference to  FIG. 1  for a schematic view of the basic configuration of a page-type seven-color automatic printing machine  10  of the present invention, an adhesive glue is filled into a first printing ink set  101  of the page-type seven-color automatic printing machine  10 , and a second printing ink set  102  is modified to be a cold stamping device  20 , and a drum-shaped foil  21  is mounted, and printing ink sets  103 ,  104 ,  105 ,  106  at the middle sections are filled with different color printing inks respectively according to the printing requirements, and a repulsive paint and a gold paint are filled into the last printing ink set  107 . In a printing process, the first printing ink set  101  is provided for partially coating an appropriate amount of adhesive glues onto a printed matter  30  by a printed flexible board  40 , and then a stamping press board  50  installed on the second printing ink set  102  is provided for attaching a foil material  21  with a corresponding pattern partially onto the printed matter  30  (which refers to the portion coated with the adhesive glue) by press adhesion method, so as to complete the required partial cold stamping operation, and then four printing ink sets  103 ,  104 ,  105 ,  106  at the middle section are provided for completing each expected color printing operation in the same-line procedure, and then the last printing ink set  107  is provided for coating the repulsive paint and the gold paint onto the printed matter  30 , so as to complete the same-line operation of printing a ground or snowflake-like printed pattern onto the printed matter  30  according to the mesh size (not shown in the FIGURE) of a mesh ink roller B attached with the gold paint. The invention can improve the printing efficiency and production capacity in order to save the total printing cost significantly. 
     The larger the mesh size of the mesh ink roller B, the more ink of the gold plant stuck on mesh ink roller B, and the larger the ink particle of the gold paint, and thus achieving the printing effect of the ground pattern, or else achieving the effect of the snowflake-like pattern. 
     The present invention uses the page-type seven-color automatic printing machine  10  and the appropriate additional installation, modification and production of the soft printing board  40  and the stamping press board  50  to fully utilize the existing equipments to improve the production capacity and reduce the manufacturing time and cost, so as to maximize the printing performance of the page-type seven-color automatic printing machine  10 . 
     Since the page-type seven-color automatic printing machine  10 , cold stamping device  20 , foil material  21 , and the soft printing board  40  and stamping press board  50  used for coating are basic printing equipments, and thus they will not be described here. 
     The method of producing the printed product in according to the present invention is described below: 
     The water-absorbing printed matter  30  refers to a paper material that can be printed with colors. A partially stamped portion is adhered onto the printed matter  30  by the foil material  21  and the stamping press board  50 , wherein the partially stamped portion is comprised of different colors and different patterns or lines. 
     A general colored layer having different colors is printed onto the printed matter  30  to produce the desired pattern. 
     A repulsive paint layer is coated onto the general colored layer. 
     A gold paint layer is coated onto the repulsive paint layer to form a ground or snowflake-like printed pattern. 
     The page-type seven-color automatic printing machine  10  is a conventional printing machine and refers to a single printing machine with a group of seven printing ink sets, and each ink set can contain an ink of a specific color (such as any one of the primary colors) or a specific paint (such as a gold paint or a repulsive paint), and a mesh ink roller and a soft printing board are provided for printing a pattern with the color ink or the specific oil in the pattern printing process. However, the operation mode and procedure are prior arts, and thus will not be described in details.
