This document replaces GB/T 17934:5-2012 "Process control of printing technology halftone color separation films, proofs and printed products

Part 5: Screen Printing", compared with GB/T 17934:5-2012, except for structural adjustment and editorial changes, the main technical changes are as follows:

a) The requirements for substrate, ink curing color, tone reproduction range, tone value increase, etc: have been deleted (see 4:3:1 and:2012 edition):

4:3:2);

b) Added digital file delivery and plate quality requirements (see 4:1:1);

c) The requirement for the sum of tone values is deleted (see 4:2:6 of the:2012 edition);

d) Modified the calculation benchmark of image position tolerance, and changed the color separation sheet to grid width (see 4:3:2);

e) Appendix A is deleted (see Appendix A of the:2012 edition);

f) Added Appendix A "Example of Process Measurement and Control Strip", Appendix B "Colorimetric Data Correction of Substrate Color Change" and Appendix C "Different Colors"

Introduction

This series of documents establishes process control parameters and their target and tolerance values for the most important professional printing processes in the printing industry: This article

Pieces that require printed product colors to match a characteristic data set or to match printing conditions agreed upon by the producer and recipient, and specify communication and production

Minimum requirements and tolerances in production: Specific parameters that may affect the final result (screen angle, resolution, screen mesh) are also provided:

Specifications and Tolerances:

This document is part 5 of GB/T 17934 "Printing Technology Mesh Color Separation Plates, Proofs and Process Control of Production Printed Matters"

point: GB/T 17934 is intended to consist of eight parts:

--- Part 1: Parameters and measurement methods;

--- Part 2: Lithographic offset printing;

--- Part 3: Newsprint coldset offset lithography;

--- Part 4: Publishing gravure;

--- Part 5: Screen printing;

--- Part 6: Flexographic printing;

--- Part 7: Proofing process using digital data directly;

--- Part 8: Verification print production process using digital data directly:

Since products produced by screen printing can vary widely in size and viewing distance, as part of the screening and resolution requirements, both

The viewing distance parameter is included:
