Photo Paper Common Sizes
Photo Size is dimension or length and width according to R series as international standards, unit in mm (millimeter or millimetre) and can be converted into cm (centimeter or centimetre) or inch (in). In this case the size is determined based on demand.
Standard photo print sizes included into the category of R Series including 2R, 3R, 4R, 5R, 6R, 8R, 10R, 11R, 12R, 14R, commonly used on paper types for printing photographs or other measures. In present time there are many types of photo paper that is often used for photo printing, for example, glossy and matte photo paper.
R Series Photo Paper Sizes
R Series photo paper size dimensions according to the standard can be converted into unit in mm (millimeter), cm (centimeter), or inch (inches). To get the value in centimeter, it can be converted from mm to cm by divided by 10.
Photo paper is widely used in general throughout the world. Photo Paper R Series is a standard measure commonly used in the various countries.
Photographic paper is a paper coated with a light-sensitive chemical formula, used for making photographic prints. When photographic paper is exposed to light it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from fixing and clearing, though latent exposure is also usually present.The light-sensitive layer of the paper is called the emulsion. The most common chemistry was based on silver salts (the focus of this page) but other alternatives have also been used.
The print image is traditionally produced by interposing a photographic negative between the light source and the paper, either by direct contact with a large negative (forming a contact print) or by projecting the shadow of the negative onto the paper (producing an enlargement).
The initial light exposure is carefully controlled to produce a gray scale image on the paper with appropriate contrast and gradation. Photographic paper may also be exposed to light using digital printers such as the LightJet, with a camera (to produce a photographic negative), by scanning a modulated light source over the paper, or by placing objects upon it (to produce a photogram).
All photographic papers consist of a light-sensitive emulsion, consisting of silver halide salts suspended in a colloidal material – usually gelatin- coated onto a paper, resin coated paper or polyester support. In black-and-white papers, the emulsion is normally sensitised to blue and green light, but is insensitive to wavelengths longer than 600 nm in order to facilitate handling under red or orange safelighting. In Chromogenic colour papers, the emulsion layers are sensitive to red, green and blue light, respectively producing cyan, magenta and yellow dye during processing.
Matte Paper looks dull and lusterless. It is used in industry to produce good quality prints but it doesn’t have a vibrant colour finish. Matte paper is not glossy and therefore finger marks or glare from the sun are not a problem. A good use of matte paper would be inside a shop in which the lighting might cause reflections. Due to the non-reflective nature of this paper, it would be ideal.
Glossy paper is the most common paper for printing photos. It produces a sharp and vibrant image. Glossy paper is also very smooth to touch. If you need your images to be as sharp as possible then you might want to think about using glossy paper.
The best example of a gloss laminated paper is in the form of a postcard. The main photo is on the front, along with a gloss laminate coat applied, which makes it even shinier. The back has the texture of plain card stock. Laminating the paper makes the colours even more vibrant. If you plan to do any sort of advertising, then glossy laminated paper stands out above others and should be your choice of paper.
It is possible to print an image on standard glossy paper then coat it with a ultra violet garnish before finally drying it by exposure to UV radiation. It makes the image extremely shiny and glossy. UV gloss can also be used on specific areas to make them appear bolder and stand out above the rest of the design. This is often advertised as spot UV.
Stickers are often printed onto glossy paper with a sticky back which you simply peel off. The glossy paper gives the stickers the shiny look.
Pulp is a dry fibrous material prepared by chemically or mechanically separating fibres. Pulp is normally used for business cards and beer mats. When using this style of paper, you often have to make your photos slightly lighter to compensate for the darker style of paper.
