Plate making machine proofing process:
A: Proofing in front of the plate making machine is the process of indexing the proofed RIP to directly interpret the electronic document, and under the control of the color management, the print proof is consistent with the printed matter on the printer. The process of proofing before the plate making machine is printed by FM screen. The image, graphic and text information can be accurately reflected, but the result of the final output RIP and the structure of the printing dot can not be completely accurately reflected.
The advantages of the platesetter are: fast speed, relatively mature application technology, and low requirements on hardware and software. The main application in design proofing, pre-press process proofing and partial contract proofing is a digital proofing process that is currently used more. Due to the multiple RIP output or the multiple output of the same type of RIP, this process requires good compatibility between the digital proofing RIP and the final output RIP, and requires high technical level for the operator.
Second: the proofing after the plate making machine is generally the index code proofing RIP output of the 1-BitTiff file generated after the final output RIP, under the control of color management, the printing proof process with the printing quality is obtained on the printer. The 1-BifTiff file used for proofing after the platesetter contains all the information of the output layout, including all the information of text, layout, image, graphics and printed dot structure, so the digital proofs output according to this are most faithful to the final printing effect but due to 1BitTiff The amount of file data is huge, and the hardware and software requirements are very high in the actual production and operation process.
