When creating Web and app interfaces, most designers slave over every single pixel, making sure it’s got exactly the right color, texture and position. If you’re not careful, though, some common functions like moving, rotating and pasting can undo your hard work, resulting in a blurry mess. But with some small changes to your workflow, you should be able to maintain the highest-quality artwork from the start to the end of the project.
Pixel perfect rotation
If you’re not careful, rotating layers in Photoshop can damage them in a very noticeable, pixel-mashing way. When rotating layers with Free Transform (and some other tools) to exactly 90 or 270°, the quality of the outcome is determined by the layer’s size. If the layer is of an even width and even height, then you’ll be fine. If it’s of an odd width and odd height, you’ll also be okay.
Pixel Perfect Vector Pasting
If you’ve drawn pixel-snapped artwork in Illustrator and pasted it into Photoshop as a shape layer, you may have noticed that the result is not quite what you expect (i.e. a perfectly sharp image), but rather a blurry mess. Here’s how to fix that. Below is some artwork as it appears in Illustrator: perfectly formed, snapped to the pixel grid, and at the size we intend to use it in Photoshop.
Pixel perfect vector nudging
When nudging vector points, Photoshop exhibits some strange behavior, related to how far you’re zoomed in. At 100%, nudging with the arrow keys will move your vector point exactly 1 pixel. At 200%, nudging moves the point by half a pixel. At 300%, it moves by a third of a pixel. The behavior seems intentional, but it’s not usually what I’m after. Most of the time, I want to nudge in whole pixel increments. Here’s how you can do that, without zooming out to 100%.
Using the correct techniques, it should be easy to place pixels exactly where you want. Remember, you’re the one in charge. Demand that they fall in line. Accept nothing less than pixel perfection.
