1 Minute To Understand The ‘PASS’ In The Printer

I believe that we will encounter in the daily use of the MYJET printer work we often mentioned a ‘pass’, in fact, in the parameters of the printerin the print pass should be how to understand it? English ‘pass’ is ‘through’ meaning, will not be in the printing device ‘pass’ is also through the direct meaning?

 Here we can say that it is not!

 In the printing industry, ‘pass’refers to the number of times the screen needs to be printed to form (the number of times the unit area is covered), the higher the number of PASS the slower the speed of printing, the relative quality is also the better, or else on the contrary, generally in the inkjet printing equipment such as photocopiers, the more common is the 6pass, 4pass printing.

In large format inkjet printers, the print head moves back and forth on the paper to print. The ‘PASS’ represents the number of times the printhead passes over the same area of the paper. For example, MYJET-2580B multi-PASS printing may be used when printing high-resolution images or screens that require strong colour coverage. Each additional PASS will cover another layer of ink on top of the previous one, resulting in fuller and more even colours and richer image details, but the corresponding printing speed will be slower because the print head needs more time to complete multiple scans. Such as: playing a 4PASS map, each pixel needs to be divided into 4 times to cover the print to complete, usually increase the number of PASS can improve the image quality. PASS represents the print time to print a line of complete print map print head to run the number of trips, inkjet for the line of print mode, 4PASS is 4 trips, and so on.

PASS number and the picture is related to the degree of refinement, the larger the value of the print out of the better results.
