C4D Rendering for print


#1

Hi guys, long time stalker, first time poster.

I’ll get straight to it >

I’ve been working on C4D for over 5 years now, but recently tried rendering my artworks to be printed on large format.

However I’ve run into problems with the general colour space / Adobe 1998 / ICC profiles / Gamut etc.
I’ve been told C4D renders to no Gamut therefore there is no way to match for print except by eye. Can anyone confirm this? The colours in Photoshop that I’m having the biggest problem are the ones that go out of gamut and set off the gamut warning.

When I chuck my printers ICC profile to soft proof the image in photoshop (I do some touch ups in PS before exporting as a .tif for printing), the colours get washed out and even when I try everything and anything (adjustment layers, curves etc) it just doesn’t seem like what I see on screen. This was confirmed when I did a test print and it came out horrible.

I’ve been rendering everything super high res (300DPI - close to 10,000px in width and height) and printing to exact size as to not loose any resolution or quality.

My printer told me Adobe RGB 1998 is the industry standard for large format printing and that CMYK files are mainly used to pre-press proof files for offset printing (his words).

By doing some research I realised the first step was to get a proper monitor (Dell UltraSharp UP3216Q) and a screen calibrator (X-Rite i1Display Pro Colorimeter), but does anyone have any tips on this process? Everything I’ve found on the net is from 2010 and quite out dated. I’ve been creating artworks specifically for printing but I’m worried that everything I’ve been rendering is going to go to waste as when the colours wash out they don’t look as good.

I’ve uploaded a screen by screen comparison of the C4D rendered image in the native linear color space it rendered in, and on the right hand side when applying the ICC printing profile. See how the colours are washed out?

Hopefully finding some answers here will help my sleepless nights.

Cheers,
Aimos.

You get best result in a printing house with right color profile. My 2 cents

Back in May, I ran into many of the same problems.

ahaven is correct - the profile is the key. And note - not all printers offer the same quality. I would always ask to see similar output before committing. And the good ones will have some advice.

  1. Key for me was obtaining a good proofing system - printer, monitor & calibrator.
    I purchased Canon Pro 10, Dell Ultrasharp 27, and Spyder-Pro. In retrospect, wish I would have purchased the X-rite, as they offer printer calibration as well.

  2. Used both Octane & Redshift, and rendered in linear space for both.

  3. In photoshop, would use various adjustment layers and output to the Canon. Based on these results, would make adjustments.

  4. The resultant workflow would generate a number of possible outputs, which I would then get proof prints - not ones to view on monitor - but physical. Based on these, the final workflow would be obtained.

Of note - I fought the monitor calibration a bit in the beginning. It was interesting to see monitor brightness measurement required half the brightness Im used too - which would leave many images looking flatter. In fact I would override the settings a bit. Eventually realized this was in error - being spoiled by not only the gamut of todays monitors, but the luminosity. Old habits I guess.

Another interesting tidbit - work next store to a large format printer - they do trade show backgrounds, car wraps - they don’t print on papers that I wanted, but the price is right (free), and Ive printed a few things to hang in the office. Output here was generally trouble free and looked great for the venue! Some of it has to do with the glossy material, absorption, but undoubtedly not having the same steep expectations.

I do architectural visualisations some for web and some for print. There are some expectations for large prints for outdoor marketing. I use Adobe Illustrator to make the layout and place cinema 4d render saved as cmyk version in photoshop. You may have to tweak saturation value to make it look correct. If you use bitmaps then best is TIFF format. Finally I have also checked gamma value in irfanview with pc. Image may be too bright or dark if it´s not correct.
