Printing high quality A1 poster

[maryamtafakory]

Hi everyone.

 

I'm having difficulty finding a solution for my problem and I'm sure there is someone out there who knows how to solve this!!!

 

I have an animated film which I'm trying to make poster for!

The poster is going to be A1. Of course needs to be highest quality, no pixilations!!

One of my friend suggested 600DPI! but I dont even know how! as I don't deal with vector! the image I'm using is a still from my film! and my film is a full HD 1920*1080

But I'm guessing even though this is full HD for film, it isn't sufficient for printing?

 

Any way I can make this work? or do I have to create the image again on a higher resolution?

 

I greatly appreciate any advice.

Thanks

Do a test print and see how it looks. A1 you MIGHT be able to get away with the 1920 x 1080 size.

Digital print vs Press will also determine the quality you need. Without getting into the complicated side of things (and from my personal experience) DPI is only relevant if you are on a press and have someone who doesnt know what they are talking about on the other end printing it. So... our practice in the office is to work in Pixel sizes. Again, this is OUR workflow and what we prefer.

 

So for A1...what WE would do...test the 1920 first and see if it gives us the quality we need.

Probably render it out at 4K if time permits. We did a 6 foot wide print on digital with a 6000px with zero loss in quality

you need to re-render it out again at a much higher resolution

it will need to be around 10k

 

(9933 x 7015 to be exact for A1)

 

not sure if your textures will hold up to that resolution though...

if you are serious i would make a new scene especially for the poster rather than a straight frame from the animation

Sheez...A1 is pretty standard for rendering...3000px will fit on A1 no problem...most of my stuff I render out on 3000px....prints on a1 no probs.

[Nic H]

well if that works for you thats fine.

generally for print stuff the standard is 300dpi / A3 = 5000pixels

[marius e]

I have sent a 4000px 150dpi image to get printed on 3 meter wide print billboard, for upclose viewing, had no problem with it at all....

 

This 300dpi (must have for print) is a bunch of crap! No one can see the difference....Digital printers that your architects use and the professional printers are pretty much the same. Most 3d's get printed on A1, thats how they present. You guys actually rendering out at such crazy sizes?? I have never had an image pixelate or bad quality at those sizes....

 

Not sure if mental ray's filter is better for that vs Vray maybe?

[Nic H]

if you can get away with it thats good. faster renders for you.

 

recently had to do 9k renders to match in with the photography shot on a phase 1 p45 back...

that was tough...and rather long render times

[marius e]

Not saying that its not true, if one has the time to do something like that then do it, but the difference is so minute that it almost makes it not worth that effort..

[marius e]

Does vray renders pixelate rather quick when stretching slightly?

[Nic H]

couldn't say if it was worth it but it is pretty common.

i prefer working at as high a res as possible, makes photoshop and post easier and nicer to work on

looks even better when downsampled as well!

Does vray renders pixelate rather quick when stretching slightly?

 

no this isnt related to a render engine.

 

you can also use 'fractal enchance' pro or something like that if in a bind. they do a pretty good job of upscaling when compared to photoshop upscaling.

[marius e]

what I do is, set render size to A3 200dpi.........thats 3100px approx. Just a perfect size for handling in photoshop with people and all extras, plus rendering time is great as well and prints great on A1.

I disagree...we have done plenty of prints on digital twice the size of A1 and have never had to go over 6000px

If you believe Cinema 4d Render settings, then the optimal solution for an A1 would be 9933.071 x 7015.45 Pixels at 300 dpi.

 

If you have the time to render it, do it.

 

If you dont', you have several options:

 

 

1. Render half (or less) size at 300 and then double it up in Photoshop (with the interpolation method for enlarge)

 

2. Render full size but with only 72 dpi.

 

3. Render half size (or less) with only 72 dpi (the fastest but I would not recommend it)

 

 

Based on my experience you DO see the difference between 300 and 72 dpi. But it depends on how close you go and how much details you want poeple to see on your poster.

 

The HDMI solution I would NOT recommend, unless people will only see it from a far distance.

 

Pixels is mostly not the problem, since when you enlarge it to the right size in Photoshop, the worst thing that could happen is that it will get blurred.

 

So yeah, thats what I can tell you from my work experience...
