Black, not piggy Graphic designer using Photoshop or Illustrator to design Artwork, send it to the printing house, especially the work. With pieces that need to be detailed, content, letters that must use a lot of black, such as standy signs, roll-ups, leaflets, brochures or product label printing, I believe that many people will encounter problems. When sending the job file to the printing house for final inspection and print a test You may see that the black color of the sample is distorted. Instead of getting completely black, another color was replaced. Today we have some tips for choosing a color system and setting up a color system for artwork. Send to the printing house.
First of all, let's talk about the color system used in the design of the printing house. There are two common color systems used in design work, RGB and CMYK. The two color systems are different. and suitable for use in different types of work If a specific designer designs artwork , send to a print shop, signage, printing house, such as work , standy sign, roll-up, poster , vinyl banner , banner, flyer , brochure or small size like When printing product labels , the color system must be set to CMYK because CMYK is a color system based on the primary color of the print, which is cyan ( CYAN ), magenta ( MEGENTA ), yellow ( YELLOW). ) and black ( BLACK ) , therefore for safety Designers should set the color system of the work to be printed to CMYK in the first place and check the color to be sure (Color Picker).
From the picture above it can be seen that we have set various black values, but On Screen in CMYK mode gives the same black result. But when actually printed out from various printers, we will see the results of the injected ink mixed out according to the proportions that we set in the CMYK color value set. Therefore, we must observe the black color for sure. before that it is exactly what we want by looking at the numerical value Don't look at it with your eyes, we can see the color from the screen, it's not always accurate.
Special tips, especially if you want your prints or other prints with black elements to come out beautifully black with 2 color settings:
1. Intense black for small areas such as letters, thin borders and very small areas. Set the black color with CMY to 0% and K to 100%.
2.Intense black color for large areas such as logos, extra-large text or the background of the job, with C set to 30%, MY to 0%, and K to 100%.
But if a designer wants artwork for online media that is displayed via a computer or monitor of various devices, the RGB color system is the right color system and makes the presentation more beautiful. Because RGB is based on The use of primary colors is red (RED), green (GREEN) and blue (BLUE ) by the principle of color mixing is caused by the refraction of light. This makes this color system suitable for use in screen presentations.
from the difference in display in the aforementioned color system If you want to use solid black for various printing such as vinyl signs, posters, standies, flyers, labels, etc., and display them on a dual monitor. To get the highest quality of work according to usage We recommend designers Increase the episodes and waste a little more time. Make sure that the color settings are set. And must separate the design, but the color system from the beginning is the best. Although it is possible to convert the color system from RGB to CMYK for printing to a printer. But it will definitely get a color that is distorted from the customer's specification. In the end, it's time to do it again.
I believe that the techniques that we bring together today will be useful to designers, especially designers who design artwork for printing houses. This makes finishing the job easier. Don't have to face the problem of distorted color, black, not close anymore.
