The function of the RIP is to send instructions to the film processor, telling the processor where to place each item and what angle each item is to be placed in relation to the other items on the film or combination of films used in creating the image. RIP – Raster Image Processing………… a computer language that arranges the dots, solids, lines and type in a particular pattern concerning densities and angles. When the cyan, magenta, yellow and black plates are aligned and brought into focus, the printed piece is considered to be in register. Registration – The alignment of dots in relation to each other. Magazine examples that are perfect bound are Photoshop User, Mac Design, Graphic Arts Monthly and Communication Arts. Perfect Bind – A type of binding that combines the cover and the inside pages on the spine with glue. Offset – The printing process that uses a blanket to receive the ink from the plate and then impresses it onto a sheet of paper as the paper passes between the blanket and a hard steel cylinder called an Impression Cylinder. Moiré – A pattern that is created from incorrect screen angles seen in the CMYK printing process This is an evolutionary segment of the print world and the technology, chemistries and equipment are constantly changing. The printers that are used are typically inkjet or IRIS printers. ![]() Printed pieces would include large posters, POP(Point of Purchase) signage and banners. Large Format – A term that describes the printing of large sized substrates. The terminology is useful in production scheduling and estimating because it determines the quantity of the run and the efficiency and speed of the press and the operator. Impression – Each time the sheet passes through the press and is printed, it is an impression. Halftone – The screening of a continuous tone image, converting the image into different sized, yet, equally spaced dots. This material will be placed over the printing plate and with the use of light, burning the image into the printing plate, determining the ink receptive areas of the plate. When pressure is applied, the paper takes the form of the die.įilm – A sheet of material that is processed with the image on it. A process that bypasses the use of film when creating the image that is receptive to ink on the printing plate.Įmboss – Impressing an image by forming the paper using a die that is cast in the shape of the image you want to create. This is only a generalization and the densities that are run should be left up to the press personnel.Ĭolor Density – The amount of ink printed on the sheet.ĬTP – Computer to Plate. While there is a wide variance in the numbers used, the average range is:Ĭyan and Magenta reading around 135 to 145……… Yellow around 105 and Black anywhere from 175 to 210…………. ![]() It has a numerical digital read out and the higher the readout on the densitometer, the greater the amount of ink that is being laid down on the sheet. Following this sequence allows for brighter imaging and better control of color.Ĭolor Densitometer – A piece of equipment used by press personnel to determine the density of the ink color being laid down on the printed sheet. The most opaque color, black, is laid down first. Black, Cyan, Magenta and Yellow, the most transparent of the four and containing the most varnish in the formula is yellow and is laid down last. On the printing press they are run in a specific order. Although not totally complete, the terms listed below will get you well on your way to understanding your printer and the language that they use.īleed – A bleed occurs when your color or image extends off of the printed piece, typically bleeds are created when the printed piece is trimmed.ĬMYK – Cyan, Magenta, Yellow and Black are the colors used in 4 color process printing. Below is a small list of terms you will run into when talking with your printer. Terms –īefore we begin, printing has an unusual terminology that is attached to it. ![]() It is “Printing” after all, so you just have to get used to it, right? NOT! By following a few guidelines and understanding what actually happens to your files once it leaves your hands, a lot of problems can be avoided. Don’t throw in the towel and stop freaking out. It happens, and it happens a lot more than you think. The printer doesn’t have the fonts, the files don’t work, the paper you ordered isn’t made anymore and you forgot to add bleeds in your files, and when your head is reeling and your freeking out, they tell you they can’t possibly make your deadline. you have written the address of the printer you have chosen on the package and you have handed it to the Fed-Ex guy. You have written your instructions to the printer in great detail, you have packaged your CD carefully………. So, you have received a final approval on your design project and it is time to put the message in print.
