Pixel Perfect and Vector Shapes in Photoshop


Pixel Perfect and Vector Shapes in Photoshop

One major thing I have found to be lacking or just outright missing from the basic education of graphic designers is the concept of pixel perfect design. Yes pixel perfect design has nothing to do with print media, but it does have everything to do with any media that will be presented via a screen of any kind and I think that cover more then a significant enough percentage of the projects making up the work loads of graphic designers today. So what is pixel perfect design and how can you incorporate it into your daily workflow?
Pixel perfect design is the process of aligning and sizing all of the objects that make up a design/layout to exact pixel placements and sizes.
“So I am off by 0.3 of a pixel, what’s the harm!” I can remember these words ringing in my ears at around 4:50 AM in a college computer lab only a few hours before a friend’s final assignment was due. I was trying to help the friend who was in their last semester of a graphic design diploma, finish up a web design project and they are getting madder and madder as time ticks by and all their images are coming out a little blurry compared to how they see their design in Photoshop. But after a quick demo, I have them seeing the light and rushing to do a number of small fixes to their project before the deadline is upon them. And yes, the images are now coming out clear and even at a smaller file size too!
The demo was a simple one, I took a simple black coloured shape on a white background and aligned/sized it to exact pixels. Then I resized the shape by less then a full pixel as well as moving the shapes alignment by less then a pixel. After exporting the two shapes into their own image files, the results were clear. the first came out just how we viewed it while working in Photoshop. The second came out blurry. So how about we give this a try but with a little more complex of a shape.
