Selling a camo pattern is very difficult. I recently sold three patterns that I'd been trying to sell for years. I posted mine on a hunting website classified section and a year later, someone bought it) I imagine most camo companies staff their own designers and aren't actively seeking new patterns. If you want to produce it own your own, then be prepared to invest a lot of time and money. I used to work in the textile industry doing color separations on just about every design imaginable, from Disney to Martha Stewart and yes, even a few Realtree patterns, so I know a little about the process. The patterns were engraved on rotary print screens and then sent to print mills where they would print 1000s of yards an hour. I eventually moved into the digital printing industry where it's simply a matter of printing a design straight from a computer file. Each process has it's pros and cons and which one is used depends a lot on the end product (clothing, blinds, etc.) and how much printed material is needed. Preparing a pattern for the rotary print process is very expensive but printing with rotary screens is much cheaper than printing digitally. Depending on the complexity of the design, preparing a pattern for rotary printing is going to require at between 10 and 16 colors and cost you $200-$400/color for color separations, another $700-$1400/color for screen engraving and then there are test patterns to print, any adjustments to the pattern to achieve the desired look, and so on. You're looking at somewhere between $10,000-$30,000 just for print ready screens. Digital printing is just the opposite where the cost to prepare a pattern for digital printing is relatively cheap (maybe a couple hundred dollars) and actually printing onto fabric using this process is extremely expensive ($30-$50/yard of printed fabric). Digital printing would be your best bet for a small run but at some point the cost to print digitally out weighs the rotary print method. If it's something you would really like to pursue, then go after it!
