Claim One:
1. A method of preparing a gravure printing surface or surfaces for reproducing both tonal work and line work on a single printed media, said method comprising the steps of (a) engraving the tonal work image on a printing surface, said image comprising a multiplicity of ink wells separated by a grid of doctor-blade supports with a centerline-to-centerline spacing that provides a high degree of resolution of the tonal work image, (b) and engraving the line work image on a printing surface, said line work image comprising a multiplicity of ink wells separated by a grid of doctor-blade supports with a centerline-to-centerline spacing that is substantially greater than the centerline-to-centerline spacing of said doctor-blade supports for said tonal work to provide a smaller number of intersections between said doctor-blade supports and the edges of the line work image than between said doctor-blade supports and the edges of the tonal work image, thereby to improve the continuity and smoothness of the edges of the line work image.
