Specification for the use of inkjet technology in book printing
In picture book printers, toner or ink is used to replace ink for coloring. Because the color pigment of its colorant can achieve a higher density than the production standard is012647 of offset printing, the color gamut it reflects is stronger than the printing ink. The strong color gamut, combined with excellent color management software, makes it not only able to Simulate the effect of general printed matter, and can also simulate other production effects, such as screen printing, digital printing, inkjet posters, etc., and even simulate the embodiment of high-speed rotary printing presses, and can more commonly output requests on the market.
Digital proofing is a new type of proofing technology that is based on the digital book printing system, handles page graphics and text information and directly outputs color proofs according to the production standard and specifications of the book printing; digital proofing adopts digital methods The format printer directly outputs proofs to replace the lengthy proofing process such as traditional film making and printing; digital proofing is generally composed of a color inkjet printer or a color laser printer. It simulates the color of the traditional printing proofs with digital manuscripts (electronic files) Get proofs; other digital proofs have advantages over traditional proofs in terms of output speed invariance and cost effectiveness, so digital proofs are widely recognized in the industry.
With the growth of various album printing skills, how to correctly determine the operation status of the album printing machine and objectively evaluate its printing quality is particularly important; usually the test (test) printing plate is a necessary test plate for debugging the printing machine, and digital testing As a comprehensive diagnostic and measurement tool, the version is actually an electronic file, which is designed to help printers obtain high-quality color prints with low loss and little equipment preparation time; it can both evaluate print quality and The reason for the failure caused by the failure analysis in the test printing.
As a machine debugger and an operator of an album printing machine manufacturer, they can determine the working status of the album printing machine by making copies of the test version and make corresponding adjustments to improve work efficiency.
Generally, the digital test version used for the evaluation standard of picture book printing (or digital proofing) contains different quality control targets, which are divided into three categories according to their use: diagnostic targets, process control targets, and standardized targets; diagnostic targets Targets are used for printing system failure detection such as stars, etc .; process control targets are used to monitor the status of the printing system: such as color control bars, gradation ladders, color targets, vignette, etc .; scale targets are used to measure the printing system Features: such as gray balance map, ink overprint, etc.
