Profile support

Are ICC profiles available for your photographic printers?
We don't publish profiles ourselves however we are working with the manufacturers of our printers in the hope that we can provide ICC profiles in the future.
Do you support profiles for Fuji Frontiers?
It is important to note that the Fuji Frontier printers currently strip out any embedded profiles in your images, so you should ensure that your images are submitted in sRGB. You can also use our calibration print to adjust your screen to match our output as closely as possible (see above).
Do you support profiles for Polielettronica Laserlab prints?
Yes, our Polieletronica Laserlab that produces our poster-sized prints will support images with an embedded profile; the profile which we find produces the best results is Adobe 98, so you may want to use this profile for your larger prints.

You should of course bear in mind that if you supply the same image for printing at large and small sizes - with an embedded profile - then it is likely that you'll notice a difference in the final output due to the profile being used in the larger but not the smaller prints. To avoid this problem, some photographers paste their smaller images onto a larger canvas in order to print them on the Polieletronica, trimming the prints once they receive the order. This then ensures that the larger and smaller prints all take advantage of the profile handling capabilities of the large format printer.
