Artpro & PowerLock
« on: May 04, 2009, 10:58:51 AM »
I needs some help please...

To use powerlock we have been trained to put the security screening watermark thingee in only one of the channels. So say it is a straight four color process job we would only apply the security image thingee to the cyan channel (if the cyan channel is the strongest channel). We have done a few tests already on actual printed jobs but the security watermark is so well hidden that we cant even find it!

So is it correct to place the security screening watermark thingee in one channel only? Or should it be applied to all the channels? Also, would using a higher line screen affect the results and make it harder to pick up the security screening image with the film gauge that gets played out? Any other tips or advice?

As always any advice much appreciated!  :cool:
