How Square Spot Technology reduces errors and rework, optimizing process control

A 10.6µm x 2.5µm square laser window generates a uniformly distributed rectangular dot. This reduces edge energy attenuation compared to a circular dot, improving dot outline clarity by over 40%, fundamentally reducing overprint misregistration caused by dot blur.

The square dot is precisely aligned with the printing screen, eliminating overlap or gaps encountered when traditional circular dots are spliced together. This ensures uniform ink transfer and reduces color fluctuations during the printing process.

Utilizing a redundant configuration of 19 infrared laser diodes, power can be adjusted to maintain normal exposure in the event of a single laser failure, preventing unexpected downtime and resulting in bulk waste.

An integrated temperature sensor and autofocus module provide real-time correction for ambient temperature fluctuations and dust particle interference, controlling dot deformation to within ±5 microns, significantly reducing rework due to plate defects.

The energy concentration at the dot edges allows the press to quickly reach a stable state, reducing plate paper consumption from the traditional 50-100 sheets to under 20, directly reducing material waste.

Supports precise dot reproduction from 1% to 99%, enabling large-scale application of high-line-count FM screen printing and eliminating the frequent parameter adjustments required by traditional AM screens due to ink fluctuations.
