    I use InDesign CS6 v. 8.0. Also use PDF/x-1a:2001 without changes.

    You can open the image in PhotoShop and save it without the color profile. Remember to use use cmyk mode.

    300 dpi: If you use, let us say a 800x800px image (it must max measuring 2.667x2.667 inches in InDesign. If you use it to show larger, you goes below 300 dpi. [800/300 = 2.667].

    The export Adobe PDF dialog box is identical to what I see.

    I use Corel PhotoPaint rather than PhotoShop. None of the images I’ve used have been resized within InDesign, they were resized and resampled prior to placement as I said above and they are all 300 dpi downsampled from 600 dpi or greater. You say to use CMYK mode, but that’s 32-bit colour and my images are 8-bit greyscale. Does IngramSpark’s system insist on colour images for monochrome output? That seems a bit weird.

    OK, I'm not sure what goes on with the image size.

    If you use grey-scale, then just grey-scale and tiff.

    I don't understand the 1 bit image.

    I can't see where to prevent InDesign from embedding the ICC profile.

    Given that the eproof looks fine, and that the files print just fine on my proofing printer that replicates what comes out of the Xerox machine at Snap in Hobart, I have approved the files for printing. The risk appears small.

    The 1-bit image came about because it’s a monochrome image that had already been screened. Had I left it as a continuous-tone image it would be screened a second time in the PDF, and that generates unwanted moiré patterns.

    You’re not the only one who can’t see how/where to prevent InDesign from embedding the ICC profile. It’s all a bit of a mystery. Some weeks the computer gods just go crazy. The Chrome browser informs me that my new website is insecure and not mobile friendly. Firefox, Safari, Internet Exploder etc disagree.

    Thanks for the offer BTW. I’m certain you could do that for me, but it’s the underlying cause that I’d like to ascertain. As my fellow Daynotes Gang member Jerry Pournelle used to say: “We do these silly things so you don’t have to”. :-)

    A monochrome image or line-art must be 600dpi, but you still have to make it a TIFF (maybe grey-scale as well).

    I prefer the Crome Browser, but use Firefox, because of some issues in Crome about scrolling large/long tables.

    Your website uses https so I don't understand why it shouldn't be safe.

    Do you want PhotoShop CS6 v13.0 64bit (PC or Mac)? eip@erikistrup.dk

    “A monochrome image or line-art must be 600dpi…”

    Really?

    Quite some LINE are you have there!

    I guess you will go for grey-scale with these.

    From the File Creation pdf:

    The following are recommendations and specifications that you should know when laying out
    text for a BLACK & WHITE BOOKS.

         Resolution: 600 ppi for 1-bit black & white line art
                          300 ppi for 8-bit grayscale continuous tone images

    They are not pictures I used in the book. They are just an example of 300 dpi line art I executed a couple of decades ago. I can’t for the life of me recall the resolution my drawings were scanned at, but there was no visible difference between them when printed at 300, 600 or 1200 dpi. Not even with an 8× magnifier. So I’ve gone with 300 dpi for most line art ever since.

    I guess I’d better upsample my line art for IngramSpark in future. Thankfully disk space isn’t so precious these days!

    What does 😀👍 mean? They are two empty rectangles with a pale grey border in my web browser.

    A smiling face for the first paragraph, and a thumbs-up for the second.

    Thanks :-) Obviously a typeface missing on my system. I tend to keep the number to as low as possible. I really hate scrolling through endless faces I never use...

    A lot of "faces" in  a text simply make me skip the whole text, unless they are at the end of the sentence to mark a mood.

    The proof of the book arrived and looks fine. There’s a very minor difference from Snap’s output; the pix are slightly less intense and the toner is a warmer black. I shouldn’t have any trouble recalibrating my printer to match Lightning Source’s output.
