Choose Your Postcard Design

 

You may upload your own design or create on online. The online design tool is easy to use, and allows you to upload photos, crop your images and add your own text. Your text files are proofed by prepress agents for making the files print ready. The experts at the printing service check technical issues such as image resolution, bleed setup, text spacing, image resolution, layout, folding setup, and color mode. The job is started only when the customer approves the layout and design.

 

CMYK Model of Postcard Printing

 

The CMYK color model which is also known as four color or process color printing is a subtractive color model that is used in color printing and for describing the printing process itself. CMYK refers to the 4 inks that are used on color printing – cyan, yellow, key black and magenta. Although this is something that will differ according to the print house, press manufacturer, press run and press operator, ink is usually applied in the order of the abbreviation.

 

In today’s world of printing, the key color is black, but it has not always been the case. In the initial days of printing, the colors that were used for key were black, brown or blue, depending upon whichever was the cheapest ink to acquire at a given time. Today, CMYK is used for printed color illustrations.

 

The K stands for key because in four color printing, magenta, cyan and yellow printing plates are keyed carefully or aligned with the key of the black key plate. A few sources suggest that the K indicates the last letter in the word ‘black’ and were selected as B already stands for Blue. The CMYK model works by entirely or partially masking the shades on a white or lighter background. The ink reduces the light which would be reflected otherwise. The model is known as subtractive as the inks “subtract” brightness from white.

 

In the additive color models of overnight postcard printing like RGB, white is the additive combination of all the primary colored lights, whereas black indicates the absence of light. It is just the opposite in the CMYK model. White is the natural color of the paper or any other background, whereas black is a combination of all the colored inks. If you are keen to save some money on ink and produce a deeper black tone, dark and unsaturated colors are produced with the help of black ink rather than combining magenta, yellow and cyan.

 

The primary colors and the primary pigments are mathematically related. Any two of the pure radiant primary colors (red, blue or green) produce radiation when they are combined, bringing the appearance of one of the pure non-black primary pigments (cyan, magenta or yellow). When any two of the pure non-black primary pigments are mixed, they produce a substance containing the appearance of one of the pure primary colors.

 

Halftoning

 

When you are dealing with CMYK printing, a method called screening or half-toning allows for less than complete saturation of the primary colors. The tiny dots for every primary color are printed using a pattern which is small enough that human beings perceive as being a solid color. When magenta is printed with a halftone of 20%, it leads to a pink color as the eye perceives the small magenta dots and the white paper in between the dots as lighter, and as less saturated than the color of the perfect magenta ink.

 

In the absence of halftoning, the 3 primary process colors in overnight postcard printing could be printed as solid blocks of color and hence they could only produce 7 colors – the 3 primary colors and 3 complementary colors produced by layering the 2 primary colors.

 

  • Cyan and yellow make green
  • Magenta and cyan lead to a purplish blue
  • Magenta and yellow lead to red

 

The subtractive complementary colors mentioned above roughly correspond to the additive primary colors. If they are all layered, black is produced. Halftone produces a full continuous range of colors. When the primary colors RGB are combined at 100% brilliance, they form white. The primary pigments CMY when combined at maximum concentration produce black. Shades of grey are created from equal, not maximum, brilliance of RGB or from the equal but not maximum concentration of CMY. If there is a paint or draw program like Corel DRAW which uses both the CMYK and RGB schemes these relationships can be investigated by filling in the spaces with solid colors using a single mode, and examining the equivalent of the other mode. Sometime later, you will develop a sense of how the schemes work, the way in which they resemble one another and their difference.

 

The RGB mode in general should be used while preparing graphics that are primarily intended for viewing on computer displays. The CMYK mode needs to be used while creating illustrations for the print media.

 

Postcard Mailing Services

 

A number of businesses offer a single day business turnaround time for postcard printing, but if you want to have the postcards mailed to your target audience, you need to wait for preparation and mailing turnaround. It usually takes 2 or 3 business days for presorting and preparing things for the mailing pieces. In case you have a deadline to maintain, make sure that everything about your postcard printing and marketing project is conceptualized beforehand so that the printing project can be immediately commenced.

 

The overnight postcard printing services help you prepare postcards that are ready to mail as they will abide by the state regulations. Standard card sizes can make for discounted postage rates. There are moreover different options that can be selected for mailing.
