Hi i am using this CtP for exposing waterless plates -Torray/Presstek- for GTO52 DI and want to try conventional plates
-i presume analog plates will not work so thermal CtP plates are needed right?- without tampering with laser power at all.
As far as i know laser power is increased to carve deeper in the silicon surface, unless the speed of drum is reduced.
Exposure time of plate comes to 2-4 mins
Any ideas what will happen?
Will the CtP break/burn -gods no!    -?
The plate will be over exposed?

Thank you in advance

UPDATE

Tried today with double separations -CYK and exclude margin command in separation of magenta- it looked okish but thing is, if there is a line it could go like -----_ _ _------ made a grid and will try to print and register

Quote from: DigiCorn on December 12, 2017, 05:35:49 PMI imagine you have a RIP for platesetting. You could create a color curve on the M plate through your midtones that reduces output density to match.... THIS does NOTHING for registration; merely for color. If you are using paper/poly plates in which you refer to "stretch," then no... you can't reproduce a *glitch.* Without knowing how to operate a press even in the slightest, I would attribute it to a roller/packing issue.

Fast reply 
Roller/packing/blanket/impression jacket all checked, plates are regular aluminum 0.15mm -though negative with an extra silicon coating- here is a pic how it prints a solid breakaway.
I presume you cant make middle of separated tiff file print "heavier" -meaning at gripper/tail dot say 68% middle 64% so bump 4% only at middle of sheet-.
What i meant stretch is the expansion/shrinkage of separated 1-bit tiff file -or web growth-

Soo asides printing i managed to throw myself into the beautiful -or not?- world of prepress.

I have register issues on the press, i have succeded -i hope- in getting the hang of stretch in various ways except this one...the inverted smile.

Allow me to explain...i ran a KCMY config and at M i have loss of pressure in the middle of the cylinder. This does not concern me -i lose 0.10 of density and 2-3% of dot i can live with it- but my register is off in the middle of the sheet by 0.05 towards gripper while at 4 corners are in place.

The commands at my disposal are xpansion xy,xyshear,rotation,xyshift,excludemargin no fanout sadly

So is there a way i can distort the image of magenta OR cky to match this...smile? or i am bound to print in a machine that tend to say "have a nice day you will never see rosette!"

Thank you in advance
