-All printing of my photos on aluminum is done in-house by myself using a process called dye sublimation. -With aluminum prints all the hassles with mats, matching mat colors and frame issues are history. These are intended to be hung as is. The clarity is amazing and the colors are very vibrant. - I use only professional grade dye sublimation components and equipment. -These aluminum prints are very, very lightweight. There is a sawtooth hanger on the back of every aluminum print that makes hanging them very easy. -Easily cleaned with a soft cloth and slight moisture, if needed -PLEASE note that this photograph is available in two different sizes. -I can print any bird photograph from my website on aluminum. Feel free to email me your request. There will be no additional custom printing charge.
