[Alessandro Vecchi]

Hello,

do any of you know an alternative to export a 300dpi PNG file from an illustrator vector design.

Looks like my computer doens't handle the job.

Thank you for your help!

What does "Looks like my computer doens't handle the job." mean please?

Hi,

I'm working on large files, 11000x8000 pixels, and I get an error message when i try to export, after like 10 minutes.

I have a macbook i7 2.8 with 8gb of ram but no can do.

When you are exporting as the PNG, after you decide the location and name the file, the second window that pops up has the dropdown at the top. It probably defaults to 300dpi, but you can change it there to 150 or 72 or other where you can tell it exactly what you want it to be.

Hello,

Yes, I know how to do it but Illustrator doesn't handle the size. 11.000x8.000 pixels.

Alessandro,

do any of you know an alternative to export a 300dpi PNG file from an illustrator vector design.

Maybe a nice cup of tea, high or low as desired.

Apart from that, if this is something for print, if at all possible it is better to keep everything vector, maybe by saving a copy as PDF (always make sure you keep the original AI document); if it is something for web/screen use, it will be better/safer to use the legacy Save for Web and set the exact size in pixels by pixels, or to create the artwork at the final pixel size and export at 72 PPI.

Hello,

I've already tried the tea, the coffee, the pushups, the walk around the block but always the same.

i need files for printing so I need the 300dpi and the PNG is the type of file requested.

Hi,

save as .ai and open it in Photoshop setting the resolution you need...

[Alessandro Vecchi]

Hello,

I wanted to try everything before getting back to you.

Something very strange is happening.

1) I open the .ai file with 11.000 pixels x 8.000 pixels in Photoshop

2) I Save As PNG Large file size

3A) I open the saved PNG file in Photoshop and looking at Image Size menu I have a file with 300 pixels/inch large 11.000 pixels x 8.000 pixels

3B) I look at the same file in Bridge and the File Info Menu tells me that it is a file with 11.000 pixels x 8.000 pixels BUT 72 ppi

WTF all that means??????

I'm kind of smashing my head on the wall to understand!

The PPi setting is just metadata and sort of irrelevant. When it changes, this doesn't change anything in your file.

[Alessandro Vecchi]

Thabk you for your answer.

The fact is that that's really something wrong with the file as even having, as i exported and see, 11.000 x 8.000 pixels with the famous 300 dpi, when I try to apply on the system (it's for print on demand apparel) the system not only don't cover the entire area (the requested area is 8.800 x 6.200) but tells me that the file has 192 dpi.

I really don't understand what's going on or how I can solve this problem.

[Monika Gause]

When you export a file that has a size of 600x800 pixels and you want the exported file to be exactly that pixel dimension then you need to export it at 72 ppi. You may find that wrong and maybe it even is wrong, but that's how Illustrator works.

You want to change that? Please post here: http://illustrator.uservoice.com

[Alessandro Vecchi]

I'm exporting via Photoshop.

The file is made in Illustrator and I'm opening an .ai file inside photoshop setting, when opening the file, the size to 11000x8000 that is the Illustrator file size.

The fact is that when I look at the data of the exported png file the size is correct but then on the POD system looks like smaller.

What I should do?

Than you very much for you assistance!! You're an angel!!!!!

[Monika Gause]

POD? Which POD system?

The trouble is that PPI is just metadata. Some systems just ignore it.

[Alessandro Vecchi]

Print on Demand.

The website where I'm uploading, when I place the image with the 11000x 8000, even if the canvas of the product is 8600 x 6000, my image doesn't cover all the area and tells me that the image, at that size, is 192ppi.

8600x6000 what? millimetres? feet? pixels?

Pixels is a dangerous unit. Illustrator just somewhat deducts it from inches. But nobody knows what other software does.

You will need to find out the exact specifications the online printing service expects from you. And yes, that means that you need to actually talk to them and have them explain to you how their service works.

And if the only thing they accept is a PNG, then I would rather look for a different service that can work with a decent file format, such as a PDF.

[Alessandro Vecchi]

Pixels.

Well, what I did since we are talking about vectors is that when opening in Photoshop I set to open with double of the size, 22.000 pixels x 16.000 pixel and then I've saved the PNG.

Looks like now I have a file big enough and with the needed dpi.

I hope this solution works printed and not just on screen.

Do not hope. Contact them and ask.

Downscaling large sizes (yours is large) might cause issues as well. Especially when done automatically by some server.

[Alessandro Vecchi]

I will ask for a test file so I can see the end result!

Thank you!!

[cinziamarotta]

Why png format? I can't believe that printing service doesn't accept pdf files for printing...

[Alessandro Vecchi]

Me too!

Even for photography they ask for PNG.

Since one of my projects is for my street photography, not this one, I'm kind of scared of not using .tiff files for the printing.

[Daniel E Lane]

why are you wanting a PNG for printing? Totally the wrong file format for printing. PNG stands for Portable Network Graphics. It a lossless compression algorithm to make files that look good in a web based environment. Never meant to print from. What printing service are you trying to use? If all they will take is a PNG file, you should start looking for a different printer!

[Alessandro Vecchi]

Thank you. I totally agree!

Unfortunately, for some products, this provider is considered the best.

For my photography project I'll be looking for a different solution indeed.

More than you probably ever wanted to know on the topic of PNG and resolution – why technically there is no such thing as a 300 ppi PNG, however there is such a thing as a 11811 ppm PNG:

Re: Bridge 8.X update defaults to 72dpi

If you can link to the provider, some people here may be able to read between the lines of what they ask for, or may even have worked with them. Worth a try.
