General informations
From the print file of the logo to be reproduced, as many films are created as the colors to be reproduced, each film will allow to engrave, through a photoengraving process, as many frames as the colors to be printed. The frames are positioned on a special printing machine (Carousel) and each loaded with the desired color, then in sequence they are lowered onto the product to be printed so as to transfer the ink of the desired color by pressure only through the micro-holes previously created at the chassis.
In screen printing, each color will correspond to a frame then to make the final print the various colors will be printed in sequence, drying them one by one after each print, so the sum of the individual prints will form the desired image.
- Maximum number of colors possible: up to 8 distinct colors can be printed.
- Implants and support materials: film and frame (one for each single color)
