Every day you visit your office space or walk by the streets and come across those motivational posters that help you to move forward with enthusiasm. Although the ideas or the words behind these posters are themselves very encouraging, the colorful printing of these posters brings out the liveliness in them and aptly conveys the message.
Colorful poster printing is an art in itself. No matter how good the concept is, if the poster is not printed correctly, everything goes to waste. So it is important to set the proper resolution, provide accurate colors, and then print them in the correct format. Here are a few pointers that help in the colorful poster printing process.
The camera resolution of the image
The pictures are made up of pixels. When the resolution of a picture is too low, the pixels get stretched and look unclear and absurd. Also, if the pixels are overstuffed in a small picture, then the details of the picture are lost, and the image looks bland.
The pixels of the image are dependent upon its resolution. Therefore, it is important to set the highest resolution for your pictures. In case if you want to crop your photo or edit out some unwanted things from the photo, then you can always lower the pixels of the photo, but once the pixels of an image have been compressed you can not increase them. So make sure that does not happen with your poster.
Also, when the digital format of the posters undergo the process of colorful poster printing, then the pixels are counted as dots, and the printer converts the whole image into dpi. DPI stands for dots per image. So, this means that every pixel is converted to a dot when it is being printed. Hence, there needs to be a higher resolution image that contains a good amount of pixels for the final poster to be clear.
Color modes of your image
RGB and CMYK are the two color modes. RGB stands for Red, Green, and Blue. These colors are used in digital formats and on the digital devices to display the colors in any picture. These colors are like the basic blueprint of any image and to create, edit, or merge any image you would need these color maps. When printing any image, the RGB color map is not of much help as the printing maps are CMYK. CMYK has Cyan, Magenta, Yellow, and Key. The key here is used to denote black color.
Note that both the color mapping schemes have a common color black. This is because every image has shadows and highlights. The highlights in the image consist of the bright undertones, while the shadows are made up of darker undertones. So the darker undertones give contrast to the image and bring out the finer details in the image. Hence black is present in both the color schemes.
So before printing out your desired poster, you need to convert the whole image into CMYK. The RGB colors look good on any digital screen, but after printing an RGB color-coded image, the poster might look whitewashed. Therefore, make sure to convert the image into a CMYK color code.
There are various software packages that will do the trick for you. Some common examples are illustrator, creative suite, quarkxpress, and photoshop.
These are the two basic points about colorful poster printing. The poster printing process gets complex with the designs. These basic considerations, however, apply to both simple poster designs and the complex poster designs as well.
