A poster is a very useful tool to communicate a message toward your target audience in an attractive and interesting way. Of course, it all depends on how well it is designed as well as the final quality determined by the step of poster printing.  

To understand better how to create a good poster design and outstanding poster quality overall, here are some tips you can take into account. 

1. Color processing 

There are two popular types of color processing, which is the CMYK and RGB colors. RGB color processing uses three primary colors of red, black, and blue. On the other hand, CMYK color processing, or sometimes known as the four color processing, uses four primary colors to create more color shades. CMYK color processing mixes cyan, magenta, yellow, and black. RGB colors tend to look brighter especially if printed with CMYK inks. If you design in RGB colors and print in CMYK which is most commonly used by most printers, you will get colors that are inaccurate. If you want to get the colors that you see on your screen as you design upon printing, then make sure that you design using CMYK colors as well. 

2. Design resolution 

High quality printing calls for high quality and resolution design. You can't get the quality that you want without making a design that is compatible with high quality printing. The best resolution for printing is 300 dpi, and everything included in the design of your poster must be of this resolution as well so that everything looks sharp instead of stretched and pixelated. 

3. Poster size and Poster paper stock 

There are sizes of paper stocks that you have to know and choose for your poster so that you can design with an accurate measurement. It is absolutely important because designing without knowing the right size of the poster you will print later on will get you a poster with low quality. For example, if you are trying to print an A3 poster, then you have to know the width and height for that size so that you don't design in A4 measurement instead. 

4. Final check 

Before calling it a day and ending the designing process for your poster, you have to make sure that it is free of mistake, especially once you are about to hand your design to a printing service for the printing steps. Check the color processing; make sure it is in CMYK, design in 300 dpi, and most importantly be sure that your poster has no errors in spelling, grammar, punctuation, and the information that you provide on it. An important tip to remember to make sure that nothing changes when the design gets sent to the printing service is that you have to send it in the pdf format. 

5. Printing service 

The choice of printing service plays a very crucial role in determining the quality of a poster because only with a professional printing service that has the right equipment for poster printing you can get satisfactory poster result.
