Description
Technical Field
The present invention relates to the field of printing technologies, and in particular, to a printing control method, apparatus, device, and printer.
Background
With the development of printing technology, we can now print images with three-dimensional effects or ink pictures with more intense ink using UV (Ultraviolet) printers. Of course, when printing an image with a three-dimensional effect, a large amount of white ink needs to be accumulated before printing color ink, so that the substrate part and the relief part form obvious layering, and when printing a product with a relatively thick ink amount like an ink painting, a large amount of color ink needs to be printed on the white ink or directly on a printing medium after the white ink is printed. This results in the color ink and white ink being likely to be of different densities and in a relatively large amount.
For the situation that the color ink and the white ink need multiple ink amounts, the conventional printing control method is that if the multiple of the white ink is large, the color ink is printed on the white ink after the white ink is continuously printed, so that the printing efficiency is low, the white ink needs to be positioned once when being printed, and the method is tedious and has errors. An improved printing method is characterized in that printing of color ink and white ink is completed at one time without repositioning, if the color ink in a unit printing area needs 2 passes to be printed, the white ink needs 4 passes to be printed, the white ink is printed once when the white ink is scanned, and the color ink is printed once when the color ink is scanned twice.
