Wednesday, May 19th, 2010

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.
