Abstract

The invention discloses a method for adjusting the position of a silk-screen character on an IMD (in-mould-decoration) sheet. Final correction of the position of the character can be achieved just by producing a screen printing plate for three times; a deviation value delta between the position of the silk-screen character and the correct position of a character can be measured by producing the screen printing plate for the first time; adjustment of the deviation value delta and a correction value S can be processed by producing the screen printing plate for the second time; the set final position of the character is determined, and the third time of producing the screen printing plate is based on the finally determined position of the character, so the character at a correct position can be subjected to silk screen through the produced screen printing plate. Therefore, only three films are utilized in the method disclosed by the invention; the first film and the second film are used for finding out the final character position by a test, and the screen printing plate produced by the third film can be used for final silk-screen, so the repeated production times is less, the operation staff do not need rich experience, the accuracy rate is high and the precision is high.

Description

technical field

[0001] The invention relates to the technical field of silk screen printing, in particular to a method for adjusting the position of silk screen characters on an IMD sheet. Background technique

[0002] The current method of screen printing characters is to set the character position on the film, make the screen, print the characters on the IMD sheet, and compare it with the reference character at the predetermined correct position on the IMD sheet. If the reference characters overlap, it means that the character position of the screen is the final character position. If the printed characters do not overlap with the reference character, it is necessary to repeat the test many times, adjust the character position of the film and remake the screen again and again, until Overlap the printed characters with the reference characters on the IMD sheet to determine the final position where the characters on the film should be set.

[0003] For example, it is necess...
