So you have a client (or you are the client) ordering a promotional item to hand out to their clients. Grrreat! They decide on their handout of choice and you say, “OK, I’m going to need your logo in a vector/eps format. Will you or your designer email it to me?”
Following that are any number of scenarios. Unless they’ve done this before, some painful teeth-pulling over the next few days, even weeks, usually ensues until you have the correct file to forward to your vendor, embroiderer, screen printer or ‘other-er’ who will make the final magic happen.
Here is a comparison of the differences between vector and raster images. (The next post will cover why this all matters – so stay tuned.)
VECTORS
- Formats are: EPS, SVG, AI, CDR, WMF & DRW
- Created in drawing/illustration programs (Adobe Illustrator, CorelDRAW, etc.)
- Made up of points, lines and curves
- Scalable. They can be enlarged or reduced in size and won’t lose any details
- Easy to edit
- Typically much smaller files
- Color modes: CMYK/4 Color, Pantone/Spot, RGB
- Used for: logos, branding & marketing materials (letterhead, business cards, signage, etc.)
- Able to be saved or exported to raster/bitmap formats
RASTERS
- Formats are: BMP, JPG, TIF, GIF & PNG
- Created in photo editing programs (Adobe Photoshop, PaintShop, etc.)
- Made up of pixels, each one assigned to one color
- Only able to be reduced in size; cannot be enlarged without losing sharpness and image quality
- Difficult to edit
- Typically larger files, especially high resolution images
- Color modes: RGB, CMYK, WebHex
- Used for: photographs, web images
- Cannot be converted to a vector image without either manually redrawing or relying on specific software
That’s the quick and dirty comparison. Next post will discuss why this matters.
