Chromark Corp. was established in 1960 first known as Rocky Mountain Advertising. We manufacture sign making equipment for schools, churches and businesses. In 1974, we developed the water based ink called Chromark. We still have some of the same dealers since we went to the water based ink. 

We ship all over the nation and have dealers throughout the USA. Used by cheerleaders, pep clubs, boosters, teacher, and students. Great for school & holiday posters, bulletin boards, & borderettes.

Chromark Corp. is known for our same-day shipping. You don't have to wait for your order. We ship fedex or ups. A friendly representative will answer your call with any questions. PO's accepted.
