jpg or png for printing out animated pictures?

[Bakgrund]

Hey!

 

I am going to order some pictures to be printed out. I am wondering if jpg or png is the best to use if the pictures are animated? If it matters, here's two of the pictures that i'm going to print out: http://imgur.com/a/bkfeY#VeJqf66

 

+ one is a 4k picture that is 15MB big (too big for imgur), and i noted that the colors get very very weird in the browser if i use jpg with that specific picture, when i convert it to png it gets normal, why is that?

 

Thanks.

It really doesn't matter, it won't give you a noticable difference.

irrelevant, doesn't matter

Thanks for the replies!

 

Does anyone know why the colors get corrupted if the file format is jpg in the 4k picture?

jpg was never meant for 4k really. png is more close to raw than jpg and thus better colors

JPEG is a lossy codec - you lose image quality and save space. PNG can be rendered lossy or lossless. Also, PNG supports a transparent alpha channel, which means if you want to use the natural colour of the paper instead of near-white colours you can by removing them from the image, whereas JPEG will simply raster data free areas as white, which signals the printer to ignore those areas. The images you've shown use quite a lot of white and near white areas, especially in the fonts and borders, so think about this! With that being said, PNG does not support the CMYK colour space internally - it's designed for network, digital graphics (as the name would suggest (Portable Network Graphics)), however conversion from CMYK to RGB for printing is so advanced these days it really doesn't matter.

Also, the printing process generally removes a lot of compression and colour artifacts simply because the image is (generally) undersampled and because you're using inks. In the digital pace, mixing colour generates white, whereas mixing (for example) inks gives you black. What that means is printed images will generally turn out noticeably darker than a digital image. Blacks will be blacker and whites will be whiter, and depending on the panel you're using, the colours will probably be more vibrant, and this change can help reduce or remove artifacts.

 

If you can only choose between the two, use lossless PNG, otherwise JPEG will serve you just fine. 

If the original images are rendered in JPEG or lossy PNG converting them to a higher fidelity format like lossless PNG or TIFF won't render you better results as the data doesn't exist in the first place.

+1 @CaptainSi I think it's a colour space issue. Plus photos taken RAW format tend to have a more muted color rendition when compared to jpeg. You fix this in post processing. That's why many people shoot in jpeg format for the more vibrant colours.

well the truth is: neither. What you want to use for printing is pdf. Yes the guys are right, (@CaptainSi; @Silvercall)but what you use for print is pdf. You'll need CMYK colors for printing, (so be sure to export your pictures in that color mode), you can use Adobe Acrobats ink manager (or the same option in InDesign if you use that)..be sure that your resolution is set to 300dpi. if you want additional accuracy you could also ask for printer's ICC profile then convert your files to that exact profile to avoid too many ink used during the print job, better matching of paper they are going to use (coated, uncoated) with the data your file contains and so on. A good advice is also to check the color levels and keep their overall value (C=0-100 M=0-100 etc. ) under 300 (270-280 is a safe point 'cause you never know) and your pdf file is the file format that can withhold that kind of information (as well as fonts, layers and so on...). But one thing to have in mind if you are going to use jpeg or png, text tends to look sharper in png format (lossless).

^^^^^^^^^^^^^^^^^^^^^^HARDCORE PRINT NERD DETECTED. Adding to this - PDF is very good as it's a well supported format but you need to be careful! Most softwares use lossy compression as default settings for images stored in PDFs. Usually PDFs use the FlatDecode compression algorithm for lossless embedding of images, which is exactly the same compression as PNG, so really the only difference between the two is support... when they're set up correctly.

look who's talking !   (but thanks for the compliment) - also what you've said is true,but if you are using Adobe programs (like Acrobat or InDesign) you can regulate everything. @Bakgrund It's worth exploring into this...maybe it sounds complicated, but honestly it's a not that much stuff to learn and you'll be thankful someday  if you invest your time in this. (for example when someone call's you a print nerd   )

I got my posters a few days ago, here's one:

 

 

Really happy with the resut, it was a png btw.

 

Thanks for all your help!

Nice poster glad it turned out well!
