Great Printing ExpectationsWritten by Ariel Velasco
Ideally, we would want to have printed what we see on our computer monitors exactly as it looks. But such is not case in reality. It is a fact that there exist a certain degree of difference between what is perceived from computer screens against images that are printed by printing presses.Images generated by scanners and digital cameras are combinations of three colors namely Red, Green and Blue (called “RGB”). Computers make use of these colors as well in displaying images. A different set of colors are used by printing presses in printing colored pictures. The colors Cyan, Magenta, Yellow and Black (“CMYK”) are used here and this difference will force us to make needed color adjustments. If we want to print an image with an RGB format, it is required that we convert this file to CMYK as this is format used by printing presses. Since printing presses use a standard-value conversion of RGB images into CMYK, output may not be enough for your taste. What must be done is for you to make conversion. Through this, you will have final say on appearance of image that you want to have printed. Worry not, there are software like PhotoShop and Corel PhotoPaint that you can use in conversion process. I highly recommend doing this because it certainly is worth effort to have great results being realized.

Are you looking for a printer that will not only print you text but can also give you a high quality image?Before buying or using a printer, you should know what quality you are going to get. Image quality depends on paper and printer that you are going to use. Printers are divided into two categories, impact and non-impact. Impact printers refer to printers that touch paper in order to create an image. Non-impact printers are those that do not touch paper when creating an image. Dot matrix and character printers are impact printers. A dot matrix printer has a series of small pins. These pins strike a ribbon that is coated with ink. When pins touch ribbon, it transfers ink to paper at point of impact. Character printers are just like typewriters, only that they are electronically controlled. The characters are transferred to paper by an ink ribbon that is struck by letters or numbers embossed on a series of bar or ball. Non-impact printers include laser and inkjet printers. Laser printers use a dry ink or toner, static electricity and heat to transfer image onto paper. Inkjet printers have nozzles, which spray drops of ink directly on paper. Other printers that belong to this group are solid ink, dye-sublimation, thermal wax and thermal autochrome printers. But they are not discussed on this page. We are going to focus on inkjet printers.
