Versacamm Heater settings
Can anyone point me in the right direction regarding the heater settings on the versa camm, is there a general purpose setting, what are the general guide line ie. hotter for thin vinyl, of colder for banners etc.
Just need a few basic setting to keep me on the right track till the engineeer commissions the machine.
After using the edge so long and using 72dpi as the norm, what dpi should I saving files at, from Photshop, etc for printing on the Versacamm. Need some basic guidelines to save a lot of testing etc.
Thanks in advance.

45 degrees is a good average point , generally if you can go high , do so, especially if the ambient temp is cold. If the vinyl or media tends to buckle or ruck when heated , then reduce temps a little.
DPI is totally irrelevant when saving files for digital printing , SIZE counts;)
What you need is between 120 and 150 pixels per inch of printed output IE if you want to print a 20″ x 30″ file , it should be 3000 pixels by 4500 pixels for best quality. For stuff that is viewed a long way off , you can drop to 50-75 pixels per inch.
The 20 x 30 graphic file size will be 3000x4500x3 (rgb) , IE 40 megs or so at the best resolution your printer can do (artistic or high quality) and if you take the 75 figure , it will be 10 megs.
This “rule” also enables you to scan at the correct “DPI” (actually “ppi” Pixels per inch) and it works like thisInches printed/inches of picture x 150 (or 75)
So for your 20×30 graphic , assuming you had a 5″ x 7.5″ picure , you take the 30 , divide it by 7.5 = 4 and times that by 150 , which = 600 , to to print that pic well , you need to scan at 600 dpi (ppi)
Obviously vector files are a LOT smaller.
Export out as an EPS using PS3 , and set the rendering intent for both cmyk and rgb raster and vector files as “perceptual” in the rip.
Be careful of inserted raster graphics in corel , it’s often better to convert them to bitmaps in Corel (300 dpi cmyk) and then they print saturated , often they print a sort of muted darker colour if you dont convert em.
