PNG is not the best format for printing.

It will look pixelated when zoomed in, because it is a pixel format.

Either export at a high resolution or (better) use pdf for print.

Thankyou for the reply. I exported it in the highest possible resolution (300ppi).Actually the client needs .png format only , so I have to give them in .png format only.

Samiksha,

 

I exported it in the highest possible resolution (300ppi).

 

How about Other?

 

You can also Anti-Alias.

You are welcome, Samiksha.

 

Have you tried setting the resolution under Other instead of settling for 300PPI?

Yes , I have tried 72pp and one more above that , it made the images more pixelated.

Samiksha,

 

I wonder whether the following can be of use; it may sound unforgivably outdated and boring, sorry.


If you wish to have PNGs (PNG24 (also (little) known as PNG32, it holds 24 bit colour and 8 bit Alpha channel (transparency)), of course) look crisp and clean, at least when it is (also) to be used at moderate screen resolutions, it is important to have the images in the exact desired final pixel x pixel size, or at sizes that are powers of 2 times as large (2x, 4x, 8x, and so on, the larger values can improve the appearance on high resolution screens and still ensure best possible appearance at low resolution screens); forget about resolution which may actually lead to wrong sizes and hence blurriness, or work at 72PPI or powers of 2 times as large (144PPI, 266PPI, 576PPI, and so on).


It is easiest and safest to work at the desired size when creating the artwork.


It is important to remember that a raster image represents the whole appearance, including strokes, so to make sure you get it right you can click Show Preview Bounds in the General Preferences (and untick it afterwards).


A very common unsuitable way is to Export to PNG (remember to use PNG24 and use Transparency for artwork to be in front of different backgrounds) with a medium or high resolution, such as 300PPI.


And a common misunderstanding: (almost) 11 out of 10 times, a statement like "I created the document at 300 PPI" means that the value is chosen in Effect>Document Raster Effects Settings; however that only means that the (current) resolution of any raster effects applied to the vector artwork, such as (any kind of) Blur, is set to that value (and only unless/until the value is changed to something else); when zooming in, this resolution can be seen in contrast to and on the background of the vector artwork. So this setting has nothing whatsoever to do with the actual resolution of a raster image created from the (vector) artwork (but it ought to (at least) match it).


For clean and crisp artwork avoid JPEG.


It is also important to have the artwork and also the Artboard placed fully within integer/whole pixel X and Y values in the Workspace, which means that the X and Y values at the corners must be integer; this can be ensured by using one of the corner Reference Points in the Transform palette, and then checking that all the values X, Y, W, and H, are integer (the centre Reference Point can only be used if both W and H are even numbers).


Otherwise the resulting image will become a bit wider/taller and the extension(s) will be empty and therefore be (partially) transparent/white.


Therefore, the safest way is to create the artwork at the final pixel x pixel size and use a corresponding Artboard, then use the Legacity Save for Web (where you can look in the Image Size window for size confirmation and possibly multiply by 2, 4, 8, whatever), or use Export at 72PPI (or 144/288/576/whatever PPI), or use Export for Screens (in either way). In either case, use the relevant optimization (available with both ways); it is also convenient to have 72PPI (or 144/288/576/whatever PPI) in the Effect>Document Raster Effect Settings.


If you have pure vector artwork, you can relax a bit and have the artwork/Artboard at any size (the Artboard must have the same proportions as the final image), then use the Legacity Save for Web and set either Width or Height in the Image Size and Apply (make sure the other value is also correct).


The Legacy Save for Web may be an old carthorse, but it knows its way home, even if the driver is drunk and sleeping it off in the hay in the back.

 

Or you can switch to SVG, if applicable.

Of course it looks pixelated when you zoom in...ppi resolution is relative to the output size, so the bigger you make an image, the lower its ppi gets. Zoom in enough on any image, including a 300 ppi image, and it will look pixelated.

 

All that matters are these two things:

  • What are the pixel dimensions of the PNG image?
  • How large will it be printed, in inches or cm?

 

For example, if the logo is intended to be printed 5 inches wide and must be 300 ppi at that size, then 5 x 300 = 1500 …meaning if the image is 1500 pixels wide, it will print 300 ppi at 5 inches no matter what it looks like when you zoom in. Because zooming in is not showing it at print size.

 

To make it clearer how ppi works, the same 1500-pixel-wide example would be 600 ppi at 2.5 inches wide, or 100 ppi at 15 inches wide. Because ppi resolution only means something if you say how many inches that fixed number of pixels will be spread across.

 

What is more typically done is that a PNG should be used for web/mobile use, at pixel dimensions required on the target devices. And then for print, the client should use a second version in Illustrator or PDF format, because it will be in vector graphics format, able to scale to any printer resolution. Because if you supply a text-based logo at 300 ppi and it goes to a 2400 ppi prepress device, it will look jaggy. If you supply an Illustrator file or a PDF version of it, the vector graphics can be rasterized at the full resolution of a printer at 300 ppi, 600 ppi, 2400 ppi, 2540 ppi…in other words a vector graphic is always ready to provide full detail at any resolution. Which is why many people design in Illustrator in the first place.

 

If this makes you wish there was a vector format that could do that for web/mobile, there might be: The SVG (Scalable Vector Graphics) format. If your client's technical requirements allow SVG for web/mobile images, saving the logo from Illustrator as SVG (assuming it was drawn with paths) would give them the benefits of a vector graphic that will never pixelate in both web/mobile and print.
