For many printers and printing companies, customers' dissatisfaction with color is one of
the main reasons why they lose money. When the final product fails to meet the
customer's requirements for color, the printing
company always suffers from complaints and complaints. According to the
survey, about 30% of the returned goods are caused by customers'
dissatisfaction with the color of the finished color printing products, because
the color of the products is inconsistent with what they see. (quality
standards: in accordance with the relevant regulations of the national printing
press commission, color printing shall be deemed qualified if the color
difference of color printing does not exceed 10% of the sample printing. Black
and white printing shall be subject to the signature of the customer.)
In fact, we all know that it is impossible
to achieve the same color in different batches of color prints. The color of
color printing is determined by the ink used. The color of printing patterns is
an important indicator of product quality. How does the printed matter meet the
customer's standards? What does a good printing house need to do, and what are
the problems? First of all, we need to confirm the color standard of the
customer's products. We can use a professional color difference meter to test
the standard color number of the customer's samples. Second, we can find out
the color composition formula according to the standard color number. Finally
according to the detected color composition of the formula to compound ink
color. The product printed with the compound ink can meet the customer's
standard. But is it too complicated?
The job of a printing plant or printing company is to simulate the
effect of a prototype on a printing machine. When the color space of two
devices is different, the printing plant will have more difficulty. Ideally,
the correct step would be to adjust the prototype according to the printer (so
that the printer can imitate the printer) so that the sample that the customer
sees and signs can be obtained through the printer. Designers and image
processors in their work always use the display screen as the main output
device to determine color (whereas the display can be adjusted at will through
internal Settings and contrast - contrast control).The scanning quality of
images also varies with the scanning personnel, and the scanning personnel will
create the parameters of the scanner according to the output device. However,
if one printer goes down and the printer has to use another, the color of the
image may be affected. The main solution is to use a color management solution
to help you get stable colors.
The
color management software system enables users to make color matching on
different input and output devices, so that users can predict which colors
cannot be reproduced accurately on certain special devices, and simulate the
color reproduction of certain devices on other devices to achieve accurate
color reproduction.(the work of color management system includes three steps:
Calibration of equipment, characterization and color conversion, collectively known
as 3C of color management system)
