Descriptions of Photo Paper
Nowadays, many people like printing their photo out so that can make a good memory for their whole life. So, before you printed photos you may hesitate to choosing which photo paper. And, even many people don’ t know what is photo paper. Today, I will introduce some information of photo paper.
Photo paper is a paper coated with a light-sensitive chemical formula, used for making photographic prints. When photo paper is exposed to light it captures a latent image that is then developed to form a visible image. The light-sensitive layer of the paper is called the emulsion.
History
Early photography often relied on the use of metal or glass plates instead of paper. The American Museum of Photography says that thin paper was coated with an egg white and salt solution as well as a layer of silver nitrate. The resulting single finished image appeared in brown tones, and the white areas had a yellow cast. Another later technique, developed about 1890, was Collodion paper, which utilized silver chloride and could be used to make many prints of the same image.
Modern photo paper
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. Photo paper may also be exposed to light using digital printers, 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).
Tips
Despite the introduction of digital photography, photo papers are still sold commercially. Photo papers are manufactured in numerous standard sizes, paper weights and surface finishes. A range of emulsions are also available that differ in their light sensitivity, color response and the warmth of the final image. Color papers are also available for making color images.

The Way to Get Photos on Self Adhesive Photo Paper
Creating stickers and decals
with your personal pictures allows you to use those pictures in a variety of
crafts and projects. Printing photos on self-adhesive
sticker paper is a fun option with many creative uses--scrapbook pages, greeting cards
and gifts. Preparing the images beforehand includes ensuring that the pictures
will print clearly in high quality. These templates are designed to be used
with Microsoft Word. No knowledge of advanced digital imaging software is
necessary.
1.
Purchase self-adhesive sticker paper from an office or craft store. Be
sure to buy paper that is compatible with your system--if you have an inkjet
printer, don't buy laser paper. Also, make sure the paper is the right size for
your printer. Some computer papers are designed for 12-inch wide scrapbook
pages. If your printer only accepts 8.5 by 11-inch paper, that won't work.
2.
Open up which photographs you want to print editing program on your
computer, such as Photoshop or Windows Media Center. From the file menu, open
up the photo you wish to print.
3.
Insert adhesive paper into
your printer tray. Because adhesive paper tends to be thicker, you will have
better luck inserting the paper and printing one piece at a time. Insert more photos into your
sticker template, or if you prefer, make a sheet of the same stickers. Do this
by clicking on the image you want to copy. Click on "Edit" then
"Copy." Move your cursor over the spot you want to fill. Click on
"Edit" again, then "Paste."
4.
Choose "Print" from the file menu in your photo editing program
and open the print preferences menu. Under "Features," choose the
highest quality print option and mark the option to print the image to scale.
Preview your picture.
5.
Print the picture and allow it to rest in the print tray for ten to
fifteen minutes. Because of the amount of ink used to print pictures and the
quality of adhesive paper, it may take awhile for the ink to dry. Touching the
picture right away could result in smearing.
