Many artists and photographers prefer to sell only prints, cards and other stationary items from their images instead of licensing their original images for commercial use. Many thirds party print on demand websites offer services that will help with the production of the prints and cards themselves. There are free options but usually there is always a catch and limitations. Paid services allow for room but overall it will still cost plus commission. Retain all your earnings by setting up a home photo studio lab. This will require some time and investment but then the artist or photographer will have complete control with everything including all control of costs.
One can get started on a low budget by purchasing a good quality photo printer to produce smaller and sellable 4x6 or 5x7 prints or perhaps spend a few dollars more and purchase a level entry professional wide format photo printer that is capable of larger sizes and more features. Suitable printers can be found for a thousand dollars or much cheaper if one is really lucky to come across a good deal over the internet. Canon and Epson offer high quality photo printers that produce excellent results.
The problem with using third party print on demand websites is not knowing what your photos will look like before they get to your customers. You can always order your prints before hand from the third party being used to be sure that your prints will be sellable. This normally requires purchasing your own prints sometimes with a discount but can be inconvenient because of a waiting period for shipping. It could also be very expensive if you have a lot of images you would like to sell. In many cases when it comes to the photography and art industry there is simply just very few cheap cuts when it comes down to selling your images as prints. However, all is not lost. One can invest in a high quality wide format photo printer for much less in the long run. Photo printers in this price range are capable of printing fairly large images and creation of greeting cards if so desired. If you decide you would like to sell your images as posters then this would require a much more expensive printer because of the poster size itself. Remember the larger the image the more costly it will be to produce which in turn affects the retail price of the print itself. One must consider the cost of ink and type of photo paper that is to be used when producing the images to print.
The advantages of owning your own photo printer is that you will be able to judge what your images look like before selling and if changes are needed to improve the image itself before putting to market. This in turn makes the whole process much easier, faster, simpler and much less expensive. You will also appreciate having total control over the printing production of your photographs and art in the comfort of your own space.
