Back lit media profile......

[TonyC]

I have a Roland vs640 and using Fusion back lit film (similar to Magic coat SBL-7). I have used the generic profile in versaworks for printing on this material and the prints are great. My only problem is the profile only allows for high quality printing and the printer is taking about 30 minutes per print (28"x37").
I cannot find a profile for similar material for the vs series Roland and would really like to lower the print time.
Does anyone have an available profile or recommendations on how to start making my own? Can I just maybe copy the generic vinyl profile giving me the lower quality and faster speeds with a little tweaking? Do I really need the higher quality for proper printing?
The image is just text with a slight fade and transparency in the background. There are no pictures or images.
Any info or help would be greatly appreciated as I have 90 of these to print and I don't have 45 of print time available at this time.

Backlit is usually profiled with slow speeds to achieve acceptable quality.

To achieve the required density when light is applied behind, most printers must print with multiple passes and maximum ink laydown. Also backlighting shows banding easily and a fast speed will show banding more easily than with normal reflective applications.

This rules out using a fast profile for backlit. Furthermore, unless you are very lucky, you must have a decent custom profile and cannot tweak some other profile. To achieve good imaging whilst lit, the profile cannot be built like a reflective media.
You have to use a spectrophotometer designed specifically for backlit substrates.

Thus its one of those applications where you must accept it will print slowly and quote costs / timescales to reflect this.
