silvering taking far to long going away

    Lately I have noticed that the silvering from laminating seems to be taking longer to settle down. I suppose it is due to the colder weather and not leaving the shop temp all that high, especially at night.

    I know it will go away over time, but if you need to cut the graphics afterwards, trying to get the electronic eye to see the registration marks is an exercise in futility.

    Whats a good 3ml laminate that you have found that lays down with minimal silvering.

    Well I do not use 3M anything so no recommendation from me for that but I do always rub a squeegee across the reg marks prior to loading in the plotter to help solve this same problem. But I do only see this if I do not outgas for a full 24 hours.

    I'm pretty sure he mean 3 mil, not 3M.

    3M 2 ml is great stuff BTW. Can throw it into the cutter immediately after laminating, but a little cost prohibitive for 3ml vinyl decals and such.

    I use a Summa cutter, and yes if you rub the little registration squares as the eye moves along it will eventually find them, but sometimes I like to multitask and not have to sit at the cutter for what seems an eternity while it tries to figure out where to cut.

    Our Graphtec also has difficulty sometimes reading crop marks through laminate. In its control panel there are settings to adjust the threshold - which helped tremendously. We occasionally darken some marks with a ballpoint pen or apply a small matt white sticker w/ crop marks over it, if it refuses to see it. (silver metallic material w/ Glossy laminate was the culprit)

    Keeping the shop a little warmer will help.

    Yup Metalized Mylar and gloss laminate freaks out my graphtec too, I use a small piece of scotch tape on the reg marks to matte it for the sensor.
