Canvas print

Photo canvas is a specially designed for printing fabric, reared according to the print on stretchers. The fabric looks similar to the linen fabric of painters. Traditionally, the photo canvas in the field of art reproduction is used. The method has however been successful in a very short time as a photo enlargement and found in a wide variety of consumer applications. Thus, a single motif on canvas is often used as an original decoration for home.

History

First attempts to bring photos to canvas, there was already in 1970s. On the screen a photo emulsion was applied and then exposed. After that the canvas had to be developed, fixed and rinsed. Qualitatively the method over the traditional prints was hopelessly inferior. Because of high costs and very expensive production, the photo canvas only small avant-garde artistic circles was reserved. It was not until about 30 years later succeeded thanks to digitization of almost the entire printing industry to produce photo canvas economically and in high quality. Also leading manufacturer of large format printers such as Seiko Epson Corporation and Hewlett -Packard as well as some paper manufacturers such as Hahnemühle or Canson have contributed significantly to the increase in quality of the product. So photo canvas is no longer an adventurous undertaking as 40 years ago, but a secure and repeatable manufacturing process. Now anyone can make a photo canvas in good quality.

Production

For the production of Photo Canvas Stretched Canvas fabric is used with a special coating. Only with this coating, it is possible, the enormous color range and richness of detail, providing the modern printers today represent. Moreover, the coating contributes to the life of the print at a considerably.

As with traditional photo papers also exist in photo canvas three basically different varieties - matt, satin ( semi-gloss ) and shiny. Because low-reflection surfaces usually matte screens are used. In addition to these properties, there are several surface structures. Rough canvas structures are mostly used for art reproduction, medium and fine finishes for the display of photographs. In addition, the weight and ingredients are of the canvas fabric important aspects. Thus weighs a quality canvas fabric between 350 and 500 grams per square meter and consists of at least 50 % cotton. Low weight or completely synthetic ingredients are a sure sign of poor quality photo canvas.

Be printed on the canvas with specially formulated for art reproduction large format printers. These have up to twelve -color pigment inks and cover almost completely the CMYK color space. The pigment inks are made ​​with pigments. The smaller and more homogeneous, the pigments, the better the printing results. Modern large format printers can print with a droplet size of 3.5 picoliters.

A few years ago was still printed with water-based so-called DYE ink. DYE ink was designed for short-term indoor applications. This ink is sensitive to UV light and moisture. Thus, the DYE ink begins after six months to disappear from the screen surface. The pigment ink is durable, however, under certain conditions, more than 200 years.

After printing, the canvas is trimmed and sprayed with a special varnish ( lacquer ). This step is not necessary but it helps to better surface protection. Otherwise, the screen is sensitive to mechanical effects, for example scratching.

For outdoor applications, is printed with eco-solvent ink. This solvent- based ink is designed for outdoor use. The ink is extremely durable and can easily be used for several years outside. For high quality art reproductions but the method is not suitable because only a small selection is on high quality canvas media. In addition, some eco-solvent inks escape of harmful pollutants, which makes the indoor use impossible.

After printing, the fabric is raised by means of a stapler on wooden frame and tightened with wedges. There are countless types of stretchers. Most are 2 cm thick standard Stretcher and 4-6 cm thick museum stretcher have prevailed. Museum frames are usually used in larger sizes to ensure better stability.
