Looking for a reliable CMYK uncoated colour guide book. Pantone is a little expensive (especially for design graduates), in my opinion. Is there an alternative with ICC profile and stock details specified?
I thought the same thing when I first started. Pantone really controls the market on their colors. Personally, I got my full set used from eBay for $30. They do recommend getting a new set annually, claiming the printed colors can fade on the samples, but unless you're a pro print shop, going with a used set every couple of years should suffice.
Here you are mixing 2 diferent points:
CMYK uncoated colour guide book vs. Pantone
Is a CMYK color reference search for a cmyk color atlas, cmyk color index book https://www.google.com.mx/search?q=cmyk+color+atlas+color+index
But remember a cmyk prind depends on the standard you are using, are you using european inks? Japaneese ones?
A Pantone guide is expensive becouse each color patch is printed separatedly, so you have a guide that has 2,000 diferent paches.
If your main goal is to see how a cmyk value looks when printed you can buy a color atlas.
If you need how a defined Pantone color looks, go for a guide.
If you need to see how a Pantone color looks when printed in a cmyk process, use the Bridge guide.
For a specific printer
Lets say a home printer, a digital printer on a shop there is near your home you can make your own set of patches, and send them to print. This will be the most acurate color reference there is for that particular printer.
Not Pantone, nor Uncoated, but here is an inexpensive alternative for UV Coated/Non-UV coated on standard 16pt card stock that provides CMYK printed examples of the default Adobe Illustrator Print Color Swatches for $25
