    Have just had some images printed at DS Colour labs.

    I was disappointed with 3 of the images (Ultra Pearl Finish Paper) the colour profile(too green) was wrong and the image was soft.. Phoned and complained, was told to email images.

    This is the reply I received
    These images are RGB colour space so would print great using inks but we use c-type silver halide printers so no ink involved, you need to ensure your files are SRGB colour space as an RGB file will print around a stop to dark but also very flat in contrast.
    I thought I was getting all my images printed on ink jet printers, These type of printers do not give the quality that a similar image printed on an ink jet printer.

    Another problem, which contributed to the above, I had earlier downloaded the new CC and Lightroom updates, I should have changed the embedded colour profile in the Adobe software, default is Pro RGB it should be sRGB.

    Please note silver halide printers on any paper will not give the quality that an ink jet will particularly on sharpness. A judge commented on the softness of a print last year that I suspect was printed by this method.

    Haha! Now you see why (a) I stick mostly to monochrome and (b) I don’t do prints! šŸ˜‰

    More seriously, I’m not sure where they’re getting the information that the images are plain RGB. Most cameras offer a choice ofĀ either sRGB or AdobeRGB for JPG files; and the recommendation is to use AdobeRGB as it’s a bigger colour space. But when creating RAW files, cameras actually have their own native colour space that is much bigger than either of these. You utilise much more of this greater colour depth if you process your RAW files in Photoshop or Lightroom using the ProPhotoRGB colour space. Here’s a clear explanation from Michael Reichmann of Luminous Landscape.

    When you want to output the files for printing by a lab, you should convert the ProPhotoRGB profile of your Photoshop/Lightroom imagesĀ toĀ the colour profile for theĀ printer the lab uses. It’s an .icc file that you download from the lab’s site. Here, for example, is the download page on theĀ ProAm Imaging site. (Of course, you should convert your image files to sRGB to print them on your inkjet printer in the bedroom, as it almost certainly only uses theĀ sRGB gamut!)

    (You can ‘soft proof’ your images in LR/Photoshop using the lab’s printer profile to check that your image is ‘in gamut’ on their printer, and adjust if it isn’t.)

    I’ve never had any trouble with this at ProAm Imaging, and their’s is a Fuji DP2 printer. (Fuji says this about DP2: “Type DP II is a silver halide color paper for professional use. It has a thicker paper base, a wide color gamut and a very high maximum density. It is designed exclusively for digital printing”)

    On the other hand, you could, like me, stick to monochrome PDIs: it’s far easier! šŸ˜‰
