Here you find useful information on the recommended color profile and digital file size for photographic prints.
Our preferred choice of color profile for the best possible photographic printing with our very carefully controlled ICC workflow is Adobe RGB (1998). However we do accept files in other color profiles. If you are sending us files for standard Digital Machine Prints the color profile is standard sRGB.
When finalizing your digital file for example in Photoshop you can select the color profile.
Should you need to download the color profile you can follow this procedure:
MAC users: After downloading the profile drop it into the following folder on your mac – / Library / ColorSync / Profiles folder or the / Users / username / Library / ColorSync / Profiles folder. Then restart Photoshop, open your image and choose from the top menu Edit > Assign Profile.
For PC users the path to place the Lambda profile in is WINDOWS \ system32 \ spool \ drivers \ colour folder.
As a general guide for Giclée printers, your images should be in RGB, any layers flattened and preferably saved as a Tiff file (.tif) with LZW compression. This will maximize the quality of your image and also keep the file size down. Other file formats are acceptable such as a layered tiff or photoshop document (.psd) but these will have an inherently larger file size. Jpegs (.jpg) are fine for smaller prints but because of their image lossy nature it is not recommended that you save any files in this format. Images shot as in-camera Jpegs are once again mostly suited to small to medium prints. And naturally we are happy to accept RAW camera files. Once again, please do not hesitate to get in contact if you have any questions about file formats for photographic prints.
The following table should give you a good idea of the recommended digital file sizes for different sized photographic prints. As a rule of thumb – the larger the print size required, the larger the file size must be. There is however some leeway with the image resolution or dpi and how our Giclée printers deal with this. For instance: if your image file is approximately 20MB at 400 dpi it will make an excellent print at A5 size. The same 20MB file will still make an excellent 10x8" print at 300 dpi, and a very good 16x12" print at 200 dpi. If you are in any doubt, go for a higher resolution for the print size required.
