DATA SHEET
PSR-4000WT02/CA-40WT02
Please set the exposing energy after the confirmation test of under-cut,surface gloss,
back side exposure and so on because it is influenced according to the material of the board,the thickness of ink,etc. Regarding the developing process,please control the developer density,the temperature,
the spray pressure and the developer time,etc.
The inadequacy of control causes the degradation of the developability and the increase of under-cut.
Please set the post cure conditions considering the curing time of the marking ink.
Insufficient curing or over curing may cause the degradation of properties.
