Wow, that's a news! Thanks!

Sorry for having disappeared; I tried to rebuild the previous situation but I went into troubles with the perfidious iCloud and then gave up. In this moment it is difficult for me to replicate the previous situation. I am however rather sure of what I said. The problem has been detected by my editor, using a tool called PitStop Pro. The company is Enfocus: https://www.enfocus.com/en/pitstop-pro It allowed to detect the duplicate images, that, from my side, I removed with the different layer organisation, as told in the beginning. I am trying to recover one of the old files (those with the duplicate images).

Yes, I do but for that I need my backups (now all my photos have been modified) - I can do in the weekend when I am home. The pronblem arose because the Editor checked my pdfs with some tool and he found many superimposed photos.

You are right, I was not precise. When I say "below", I say "hierarchically", so this way (this is OK): When I say above, I mean thi s way: and this construction produces multiple images. I can upload something if you like, but you can do the same as above. The problem seems not to be linked with a particular file. All that is INSIDE AP file, not inside Abu.

After having received so much from this forum, I try to carry on a little contribution. I do not pretend that what I say is completely right... it is more a suggestion to the investigation of a possible bug. One of the my biggest complains was the pdf file size, and I tried in every way to reduce it. I noted that sometimes Publisher wrongly extends the layers of an AP file outside a picture frame.See Well, this possible bug could have another kind of manifesting itself. I try to better explain: if I have a picture and some adjustment layers UNDER IT (hierarchically), all is OK. If I place these layer ABOVE the picture, the effect seems to be the same, but in the pdf file we have more copies of the picture one over the other, one for each adjustment layer. Because my book contains about 700 large AP files with 2-3 or more adjustment layers, I asked myself if the effect could be catastrophic. So I took courage with all my hands and corrected all the photos where the layers were ABOVE the picture. In this way, the size reduced from more than 9G to 3.5G and I have no more duplicated images in the pdf. I noted also that, if I have two identical image duplicated in the AP file, both are transferred to the pdf (even if the image below is not visible). And the export flag "include layers" not always has the expected result. I underline: it is just a suggestion, after one month of continuous working maybe I am confused... but it seems so. If not, forgive me and forget it.

We are starting again the same movie... The printer says that he cannot deal with a 9 GB file and I did my best with tons of tests without finding a solution. You suggested me to reduce the jpeg quality and this seems have a great impact on the size: producing a CYMK file with the settings below, with 85% the size went down to 2.38 GB. To my unexperienced eyes, it seems perfect, even enlarging much on the screen, but they refuse to follow this way. Considering that the book is only 210x210 mm, could this be a good way? Thanks Gianni

Thank you very much for your help. Now the problem has been taken out by the Editor, who is finding solutions operating on the pdf file. In the end of the day, they are getting again big files. In my opinion, the problem is without solution, i.e., if you want a certain amount of information, you need space to store it and also compression has its limits... Thanks again

Here I am again. I could succeed with the following settings: no change in document setting (RGB/16) compatibility 1.4 (Acrobat 5) colour space: RGB profile sRGB IEC61966-2.1 convert image colour spaces YES In this way, the size of the complete file shrunk from 9.1 to 3.4 G. Until now I received no complaints. Thanks again!

Thank you very much. Eventually, with your suggestions, I could succeed, but with a slightly different setup. I don't remember it exactly, I have it saved in my office computer, tomorrow I update this, but I didn't want to omit thanking you for now...

Thanks for your very detailed answer. Please tell me that I correctly understood (remember that my aim is to have a reduced size file): 8-bit CMYK = 8 bit / color, i.e., 32 bit / pixel - following your instructions I could obtain it, but the file is only 10% smaller (about) if I change from RGB-16 to RGB-8 in Photo, images go to 24-bit/pixel and the size reduces dramatically (10 times) Is there a way to obtain this reduction in an automatic way? I tried many setup but with no success. Probably I am not finding the correct profile? Thanks again

Thanks, but probably I am doing something wrong... I set the document in this way: and the exporter in this way but the pdf is produced in 48-bit/pixel (RGB-16)

I forgot: every page is an AP document, not jpeg or other.

Oh no! You again.... The last (I hope) big problem. I wrongly supposed that, setting the APu document color depth to 8-bit, all the images in that document would be converted to 8-bit in the pdf. It is not so. The images "pass" in the pdf in 16-bit, making the pdf so huge that the printer says he cannot process it (8 Gbyte). Is there a solution different from editing about 800 images by hand? (even with 3.rd party tools) As always, thanks

I understand and fully agree. I also, continuing to think, was arriving at the same conclusions. Even if I can understand the printer problem. Knowing that Indesign and QXP do the same is very important. Thanks!

I am very sorry to bother you so much, but I am delivering my work and it seems impossible to finish it. I know I owe a dinner to many of you....😀 The problem this evening is that the page bleed seems to be wrong. I get the bleed of the left page on the right page, and the bleed of the right page on the left page. If you look at the attached file, you can understand immediately the problem. Am I doing something wrong or is it a software bug? Thank you very much V2_CH2_500-Series.pdf

I didn't change it, I neither knew that it existed... 😀 But can I change it? For the photos, I was forced to change the color profile because my PowerMac M2 get crazy with the iPhone defaults - see this: Often I user Image P3, which works well. Or I left the default sRGB IEC61966-2.1.

I understand my limits.... but I must solve this problem. Thank you very much for your patience. The color space is this? However, with the color picker, black is always 0,0,0 - with the small lock open or closed. But I suppose that the printer problem is that I have a picture and behind it a black background, but it is impossible to think creating (600 pages!) a special black background for every page with a hole for the images... isn't it?

The printer is asking me for a problem. He says that "The backgrounds are in 0-0-0 RGB (black). This will be 100% black in CMYK, but certain "black" pages also have images with a black background. This then becomes a build-up color black (not 100% K but also some other C, M or Y values) resulting in tint differences clearly visible in the final product." I believe I understand that: I have a black page, obtained with black rectangle over i I placed a photo (see an example below). But which could be an alternative to that? Maybe that the problem was that I have two black rectangles superimposed? Thanks

Thanks, very useful, and thanks for the suggestions. I never could have got there by myself...

Wow, it works! In the beginning it is not very intuitive, but when you understand how it works is very powerful. Thanks!

is it possible to search a color just to know in which pages it has been used? thanks

Thank you, I understand mainly that there are many things that I cannot understand. For what I know, I never changed Color format. I will be very grateful if you can give me an answer on these point: my document is going to be printed, so the CMYK sounds good to my untrained ears; when I want the most possible black printed, have I to select 0,0,0 (so the black from Apple palette) or what I get with the second little square (231F20)? Forgive my ignorance

The second little square out of the four on the right, produces 231F20 not black. Thanks for the link, but the problem is not in printing text.

In the palette small window, there are four small squares: nothing, grey, black and white. There is a reason why the black is not exactly black? Thanks

I am the one who started this topic, so I cannot be suspected of ...connivance with the enemy 😁 I had a long experience with FrameMaker and some with Indesign and Photoshop and had some endless fights with Adobe. Their products also are not flawless and their support is simply a joke. In addition, I have several paid licenses that I cannot any longer use. I had no serious answers from them... simply they don't register anymore and eventually I gave up. All that to say that Affinity has its (many) problems, first of all APub stability. Recently things are getting better and I no longer regret having used it instead of the Adobe suite (which I still pay). IMHO, however, the best part of Affinity is this forum. Used to the Adobe support ("Did you remember switching on your computer? Many people forget its... Oh yes, it's on, but you must ask Apple, not us..."), here I can find competent people, very quick answering and trying to find real solutions together, without any politically correct attitude. In the end, beside reasonably good products and a fair pricing policy, for me this forum is the best reason to continue using the Affinity suite. Don't underevaluate it, it's a true difference.
