I'm trying to create Windows 95 / 98 pixel perfect text styles to mockup a retro UI. In the past (roughly 8 years ago) I remember being able to export BMPs from Illustrator in Greyscale and get pixel perfect, razor sharp 8-bit text. Now (Adobe CC 2018) I'm getting anti-aliasing blurry edges with everything I try. I've tried 1-bit BMP, 4-bit, 8-bit, making sure the x and y coordinates are whole numbers, greyscale, Photshop Crisp, Strong, Sharp, etc. etc. etc. and nothing is working. Your help is appreciated!
Have your text in small size. Set anti-aliasing = NONE. Rasterize. Today pixels are quite small, so you must scale your image bigger. Do it with resampling mode = Nearest neighbour. That keeps the jagginess.
In Illustrator you can trace the jaggy upscaled image generated in Photoshop, if you need it as vector for free scaling to big sizes. This is discussed here: Does anyone know how this kind of pixelated type is created?
