Black and white line drawing process

In general, black-and-white line drawing is made by photographing, revising, copying, and assisting (or imposition) black ink or better-quality prints. The film made by using this method can meet the printing requirements, but it has a long plate making period, high production cost, and the manipulation of drawings and texts is more complicated. The camera needs darkroom assignments. For the average small and medium-sized printing factories, there are also few camera equipment. .

two. Small offset platemaking process

For small-volume, low-printing printing services, such as data compilation, a small offset press is used. Its method of plate making is generally dependent on a copying machine for direct copying on a paper base plate (zinc oxide plate). This method has a low version cost, and only needs a few RMB for the 8th edition. However, the number of prints is limited, the imprinting is not true, and the copier toner cartridge must be relatively new to obtain the general effect of small offset printing.

Third, the modern plate making process

For large batches, high printing requirements, and large numbers of print jobs, scanners, computers and their typesetting software, and laser printers can produce higher-quality layouts.

1. Equipment selection

For the black-and-white line drawing, the scanner can use flat black and white or color scanners such as: Tsinghua Unisplendour Uniscan4A color scanner, the interpolation resolution of 4800dpi; computer can choose 486 grade models; typesetting software can be used to see That is, the Chinese (WYSIWYG) version of PageMaker5.0 or Founder's Fit integrated layout software, and the optional 600-point HP series printer for laser printers.

2. Several common platemaking methods:

1 Printed drafts in black and white lines with text as the main unit can be scanned into the computer using a scanner, and then TCR's OCR5.0 English-Chinese mixed printing and word recognition system can be used to convert the text department to text mode. After splicing, modifying and correcting with the line diagram, and then output through the laser printer.

2 Black-and-white prints, mainly line drawings, can be scanned and input by a scanner, and contrast can be controlled by scanning software to achieve the best results. Using computer typesetting software, the text in the original text can be translated and re-entered. The original text was covered and the sulfuric acid paper was output by a laser printer after proofreading. This method is particularly advantageous for the translation and publication of children's comics.

3 Ordinary black ink is scanned with a scanner, entered and corrected by the graphics software and corrected with the input text, and the sulfuric acid paper is output by a laser printer.
