(Sorry for the English, I don't speak German)

I read a reply of Sofja about sharpening in another topic (http://www.cewe-community.com/forum/vie ... 003#p62003). Sofja thought that some output sharpening for printing was applied by CEWE. I just spoke to someone of CEWE on the chat, and she said that no additional sharpening was performed (even when ABO is turned on, as this feature only would improve color, not the sharpness). So now I have two sources saying two different things :-). Can someone confirm whether sharpening is applied (so to compensate for the slight loss of sharpness when printing an image). See also here for more information about output sharpening for print: http://www.cambridgeincolour.com/tutori ... pening.htm (read under "STAGE 3: OUTPUT SHARPENING FOR A PRINT"). To be clear, that's the kind of sharpening I'm talking about. I wanted to know because if CEWE does not apply these sharpening, I have to do it myself. If CEWE already applies sharpening for output, I don't have to do it anymore because otherwise the image would be sharpened twice, leading to over-sharpening probably.

This might be the post you are looking for. It tells you, that Cewe marginally sharpens the pictures.

Hello Loek,

I need to agree with Rotuma. We slightly sharpen your pictures due to our productionprocess.

So if your fear, that your images might end up over sharpened you can spare the step of sharpening them by yourself.
But just keep in mind that if your not pleased with the results in your product, whether you sharpen them by your own or not, you can always contact our Customer Support to find a proper solution.

Could we please get some info about the amount and method of this "print sharpening"? Is it a kind of unsharp mask, or smart sharpen, or edge sharpen, or gaussian deblurring?

This is important for me, for I preprocess all my pictures in a same manner (generally witn no-nay-never-postsharpening, my lens do not need that :) ) and after that I choose some for the "Fotobuch". So if there is a post-sharpening, i probably need different (kinda softened?) exemplars of all pictures for the book and different for all other purposes - which would be a tremendous doublework for me lazy cat (counting all the books I make, i just gave in No. 162 with ~ 400pix in it...).

I until now seldom saw things I did not like (most on double-paged-panoramas in A4Landscape books, I only make PhotpoPaperBooks) which looked like a bit oversharpened - if you could give me these infos, I could set my camera raw scripts and my analogue-filmscanner scripts accordingly to spare me the doublework... it is very probable that it is negligible - then it deserves no more talking about, but it would be nice to know.

Thanks,

Nat

Thank you for your replies. Following the Cambridge Color link, I only need to apply 'capture' sharpening (and 'creative' sharpening to taste if I want).

It's a little bit off-topic here, but CS also told me that it's better to upload pictures at 300 ppi rather than to send with a higher resolution (like 600 ppi for example). Is this correct?

[Oldnat]

AFAIK the SW does automatically scale and upload/burn everything for300 dpi despite of what your picture had at inserting in the "book". That's why it also always fits on one CD...

Hello Loek,

Besides the fact, that your picutres will be scaled down to 300ppi, working with 600pi pictures might slow down your software, because those are quite huge files. So it is totally fine to work with 300ppi :)

and hello Oldnat,

the sharpening wich is added to your images is that smal, that you should not recoqnize it. It is only added due to the diffrent paper types and theire behavior during the printing or exposure process. So it also differs from paper to paper.

[Oldnat]

Thank you, Sonja, something the like I assumed :) Best wishes!

[Loek]

Thank you both for your answers. It's clear now. Happy Holidays :-).

[Oldnat]

The same to you

[Sonja]

I am pleased to hear that and I also wish you happy holidays :)
