Photo printer represents an easy-to-use device that operates by pressing a single bottom. A photo printer is turned on very easily and it prints photos directly from a computer or a digital camera. It should be noted that a sublimation photo printer is created on the bases of high technologies; therefore its printing resolution is higher than that by the laser photo printers. In the issue you receive pictures which correspond to a magazine printing quality 300*300 dpi. The quality of colour rendition makes up 16.7 million colours and tints. Such photo printers dispose of built-in programs that are intended for pictures’ correction. In addition, such a photo printer is very compact, that is why you can even take on the trip.

The principle of a sublimation photo printer is the following: a picture is transferred on a photo paper by the means of heating the dye and mixing of 3 colors at one point. Thus there an imprint remains on a special thermo paper. In the capacity of source materials for the given photo printers one uses film cartridges. The film in its turn has layers of hard dye stuffs which contain three basic colours. These colours are blue, yellow and purple. While heating, the dye evaporates from the film, transferring into gaseous state without any liquid transference. Such transition is called sublimation. Further the gasiform dye falls on the paper. It is worth mentioning that the printing head of a sublimation printer includes tiny heating elements. Each heating element gets warm closely equal. Consequently, dye evaporation and its absorption by photo paper depend on the temperature of the given elements. Such method of printing presupposes safe dye fixing on a paper. In the issue, the surface of the paper becomes smooth and glossy.

Nowadays the sublimation technology has found wide application in the capacity of photo printers for consumer users. The technology in question is highly appreciated by professionals of art of photos as well. Therefore the printers in question are often met at professional workshops and film-developing laboratories. It is notably, that one needs special paper and cartridges for the operating of sublimation printers.

One of the main disadvantages of sublimation photo printers consist in high costs for consumable suppliers, however there is an irrefutable argument. If you want to receive professional photos, a sublimation photo printer is the best choice for you.

Some people hesitate in the choice concerning a new photo printer. The crux of the matter is that at the present moment in the world market there is a considerable amount of photo printers, which differ in constructional properties as well as in concrete specifications. Before making the right decision on either a laser or inject printer one should examine the individual properties of these types of printers each taken separately.

As far as laser photo printers concerns, their principle of operation consists in putting the matt toner on the paper. If one takes into consideration the structure of a picture, it is notably that it will remind you of a printed photo in newspapers. On its closer examination one notices, that a photo, which was printed by a laser photo printer, consists of tiny black circlets. Therefore, the quality of printing is determined by the size of the given circlets. If a printing resolution is of high quality, in this case the circlets will be less noticeable. Thus the picture will be qualitative in tote. Currently, laser photo printers allow you to get pictures which are very close to the quality of photos. However, good quality also means high price. Laser photo printers that are cheaper are at disadvantage, concerning the quality of printing. Among the other properties of laser printers, one can single out high speed of printing.

The inject technology of photo printing enjoyed wide popularity over a long period of time. The inkjet printing presupposes the formation of a picture by the means of liquid ink, which is thrown off by a printing head under pressure. It is noteworthy that inkjet photo printers create halftones, by throwing tiny drops of ink on the paper. The drops are put over each other. In the following way a picture gets its tint and color saturation. A picture, printed by the inkjet printer also consists of definite circlets, and each of these circlets has a definite color. These color circlets are very tiny; therefore they are sightless by human eyes. In the issue, a printed picture looks like a continuous one. Different colours and tints are created by the means of the screening process. The given process implies mixing of points of different colours in a single matrix. It should be taken into consideration that screening reduces the resolving capacity of an inkjet photo printer. For all these reasons, the manufactures use different ways of rasters’ applying.

One of main disadvantages of an inkjet photo printer is the streakiness of pictures; however the latest technologies practically have eliminated this disadvantage.

Inkjet photo printers also means good quality of picture printing, their durability and a wide choice of photo paper of different types.

Modern photo printers help you to create beautiful photos. However sooner or later your paper runs out and you have to buy a new batch of it. Besides, at the present time with advancement of digital processes a great variety of paper has emerged. Therefore, before purchasing a photo paper one has to determine its type in order to get lasting photos of high-quality.

It is worth mentioning, that photo paper is created for printing of photos and graphic presentations. Thus it differs from the paper intended for usual printers. It consists of several layers, and each layer has a definite function: for example, one layer fixes the dye; the other one protects the photo from external actions, etc. An expansive photo paper of high quality has more layers. Consequently, its compactness is higher and in this case dense photo paper does not let dye ooze out on the other side of a photo. In addition pictures on dense papers are more durable.

Depending on the content of photo paper, it can be indented for inject, sublimation or laser printers. This fact should be taken into account while choosing photo paper for your printer. There is also universal paper which has the average properties; however it does not secure high quality of photos.

One can also single out glossy, semi-gloss and matte paper depending on the coating of paper. The glossy coating of a photo makes it bright by the light. Such photos, which have saturated colors, stand out against the background of the other ones. Moreover the glossy coating secures the picture from moisture, however fingerprint marks are more visible than by the matte ones. As concerns matte photo paper it is able to render even the smallest details of a picture. Physical deformations which appear on the expiry of some time are not very noticeable and besides the colors on such photo paper do not smudge. There are also single-sided and double-sided photo papers. The latter type of paper is used for printing on both sides. At the same time, the coating on each side may be either matte or glossy. Usually such paper is intended for printing of dodgers. There is also a particular photo paper which is used for photos printing and their subsequent thermo transfer on fabrics.

In conclusion it should be noted that photo paper is a very fragile material, therefore you should store it in dry and cool places. Exclude the ingress of moisture and the intensive influence of sun. These factors are also able to influence upon the quality of your photos.

Your A3 photo printer can print pictures of high quality, however there some points that should be avoided during its purchasing and managing.

In the process of scaling a picture from an A4 to A3 format you may infringe on the picture resolution. In the issue newly enlarged pictures may be distinguished by banding. Therefore before purchasing an A3 photo printer make certain, that the process of scaling a picture from small to large sizes by a photo printer can be done without this side effect. It is worth mentioning that some A3 printers are equipped with special software programs that can prevent the appearance of banding on the printed pictures.

It is also important to make sure if blotchiness does not become apparent when taking into consideration print colours both on A3 and A4 prints. This may happen in two cases: either the printing heads are not clean or the resolution of pictures is of bad quality. Ask the seller about the additional processes that can prevent the occurrence of blotchiness during the operation of the A3 photo printer. It is noteworthy that an A3 photo printer can include software which protects your photos from this side effect. Do not forget to inquire the seller about its principle of operation and installation.

The last point concerns the color resolution which plays a very important role by any photo printer. Therefore the higher the dpi resolution by any printer, the better pictures you will get. That is why an A3 photo printer should have the same resolution both for large and small format pictures. This is not the least of the factors for people who do photo printing as well as scaling. Up-to-date A3 photo printers of high quality contain scaling software that ensures good photo quality at different levels, such as A3, A4 and sometimes A2 levels.

All these pieces of advice concerning purchasing a new A3 photo printer will stand you in good stead. Consequently you will enjoy your beautiful and clear photos.
