Computer Graphic Design and Prepress Graphic Processing 500 Questions (74-77)

74. What is the production process of Indigo's color digital printers?

A: The production process of Indigo's color digital press can be divided into the following steps:

1 Design and production of documents. It is mainly done by prepress designers. They need to process and edit originals such as graphics, images, and text sent by customers, and form page files. The files also need to be set according to customer requirements for paper, fonts, etc.

2 rows. The designed electronic files are sent over the network to a specific directory of the Indigo digital press for acceptance by the press.

3 preview, adjustment, proofing. The so-called preview is performed on the Indigo digital press. After the preview, it can be adjusted accordingly, such as small color adjustment. Generally, the LUT curve is used to fine-tune the print so that the color of the print is as close to the original as possible.

Note: The color adjustment should be avoided on the printing press. On the one hand, the waste time is adjusted here. More importantly, only color fine adjustment can be performed here. If the color deviation is too great, it's best to go back to printing and adjust accordingly. At the same time, it is also possible to make a large version on the printing press. After all the conditions are met, proofs are started. The proofs and prints of Indigo digital press proofing are almost identical in quality.

4 Back to prepress and revision. If the deviation between the proofs and the manuscript is too large, it indicates that there is a problem in the prepress production section. At this time, it is necessary to go back and modify it before printing according to the actual situation until the customer's request is met.

5 Confirm paper, print. Before printing, you must check whether the paper requested by the customer matches the printing paper. If everything is ready, you can print on the machine.

75. What are the characteristics of electronic inks used in Indigo digital color printers?

A: Indigo uses a unique electronic liquid ink. Unlike traditional inks, the curing of electronic liquid inks on media is not dependent on the drying time of the ink film, but due to the high temperature of the liquid ink. At 130° C., it cures immediately, transfers the ink to the blanket, and then 100% of the ink on the blanket is transferred to paper or other media under the impression cylinder. On the other hand, the basic material of the electronic liquid ink is a new type of resin material whose shape is a polygon under the magnifying glass and is not easily diffused under the influence of pressure like the conventional ink, but is tightly combined together with paper or other media. The contact is cured immediately, the printed image is clearer, and the edges of the dots are not blurred and diffused.

76. How does a PC print to an Indigo digital press?

A: To achieve the printing of PCs to Indigo digital printers, hardware and software support are required.

Hardware: There must be network cable and Hub, because digital printing receives electronic files through the network. At this time, the current PC must be connected to the Indigo digital printer with a network cable to achieve file transfer. Hub connects all the PCs so that all PCs can access each other and form a LAN.

Software: To install the PC print driver for Indigo digital presses on a PC. Because Indigo digital presses do not accept all file formats, the acceptable file formats are: PS (EPS), PDF, PPD, TIFF, JPEG. And for CorelDRAW files, Word documents and other formats do not support, then CorelDRAW or Word documents how to transfer files to a digital printing machine? In this case, the CorelDRAW or Word document must first be printed as a print file, and on a PC, it can be printed in PS or PRN format.

77. How does the Mac print to the Indigo digital press?

A: To achieve the printing of the Mac to Indigo digital presses, hardware and software are also required to support them. Hardware must have network cable and Hub. Software: To install the MAC print driver for Indigo digital presses.
