Otherwise the resulting image will become a bit wider/taller and the extension(s) will be empty and therefore be (partially) transparent/white. If you have issues with the Artboard(s), make sure the rulers are Global Rulers (RightClick), if not change from Artboard to Global Rulers and to align your artboards, click the Rearrange All Artboards button in the Artboards panel. It is also important to have the artwork and also the Artboard(s) 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). 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).įor clean and crisp artwork avoid JPEG to get the colours right, you may wish/need to finalize by opening the PNG in PS (Photoshop) and attach the (missing) colour profile (such as sRGB) there. 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 Use Preview Bounds in the General Preferences (and untick it afterwards).Ī 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.Īnd 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. It is easiest and safest to work at the desired size when creating the artwork. 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 image 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). The following may sound unforgivably outdated and boring, sorry. When creating a logo for print, or for both print and web/screen use, you may be happier if you start by working with the artwork in the colour space used for print and keeping it vector, then (re)create a version for web/screen use. In addition to what Monika said, there are better and worse ways of choosing the actual properties when exporting for web/screen use, which may be done in some cases by saving to SVG as vector artwork as an alternative to raster formats, see below.
