"He who marches out of step hears another drum." ~ Ken Kesey
Wilflex did this and put them in a book and sent out to many of the larger companies.We got one and nobody wanted it or saw it's value, so I have it still today. It's got the inks and every special effect ink they do (did at that time). Great for presentations and showing the specialty inks. I was told it's a tedious thing to make.The easier thing for an ink manufacturer to do is to print up little squares like that above, fitting as many as you can of one or a few colors in your print area and mass produce them. You can do a run of 1000 and have someone put them together stapled or glued in a book.Heck someone could make a business out just doing that for ink manufacturers.
Did up this for our showroom a while ago during some slow time. Was the stock inks we had on the shelf at the time. QCM XOLB series. Makes it easier to sell a customer on underbases and such,but I'm not doing another one for a long time....what a PITA!
