Problems solved by technology

[0003] Lamination is an important process for the surface processing of printed matter. For a book, the cover has the highest quality requirements; in actual production, the color of printed matter after lamination will have a large difference, and the color of printed matter before and after lamination will be different. The difficulties brought about by mass production are also problems that the industry has been troubled with
[0004] The traditional method is to estimate the degree of color change after lamination, and adjust the color of the printed sheet on the printing machine. During the process, it is necessary to repeatedly compare and adjust the color of the printed sheet after lamination with the color draft to confirm whether the color matches the color draft. Use this This method often requires multiple adjustments, which is less effective and wastes valuable printing press capacity

Embodiment 1

[0068] 1. Measurement of color gamut guide table

[0069] After the electronic document is printed, when the film is produced, the color difference before and after the film is relatively large. Print electronic documents including pictures and IT8 color gamut guide table through the machine, print several copies (usually 100 copies), calibrate the CTP curve and adjust the color of the printed sheet through the G7 method, so that the color of one of the several copies after lamination matches ISO standard digital manuscript (at this time the main data of the color gamut guide table conforms to the ISO standard), take several uncoated sheets at this time, and use the X-Rite series of automatic measuring instruments, such as Eye-one iSis to conduct the color gamut guide table Data measurement to get the data of the current color gamut guide table.

[0070] What needs to be explained is:

[0071] 1) The color of the coated printed sheet matches the ISO standard digital draft, w...

Abstract

The invention relates to the field of printing, and relates to a color management method and device for film-coated printed matter. This method is mainly by measuring the coated printed sheet that conforms to the color gamut guide table of the ISO standard, and taking the measurement data of the uncoated printed sheet at this time to make an ICC profile and the ICC profile of the ISO standard for difference conversion calculation, and obtain The difference data package, using the second electronic document converted from the difference data package, is used for machine printing and color processing, and the printed sheet of the second digital manuscript whose color conforms to the ISO standard is obtained for lamination processing, thereby solving the problem of lamination The color change before and after requires multiple adjustments and the accuracy is not high. Compared with the traditional method, the method provided by the present invention is to carry out color adjustment before lamination, and solve the problem of color change before and after lamination by calculating the difference data packet, which not only improves production efficiency, but also has a higher stability.

Description

technical field [0001] The invention relates to the field of printing, in particular to a method and device for color management of film-coated printed matter. Background technique [0002] Laminating, also known as "overplastic", "mounting glue", "film sticking", etc., refers to the use of transparent plastic film to apply heat and pressure to the surface of printed matter to protect and increase gloss. Laminating film has been widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps. At present, common film-coated packaging products include cartons, cartons, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. [0003] Lamination is an important process for surface processing of printed matter. For a book, the cover has the highest quality requirements; in actual production, the color of printed matter after lamination will have a large difference, and the color of pri...
