Printing is a technical, physical, multi-step process. This is especially important for gradients and is why images require more DPI than PPI to depict the same level of detail.ĥ. Each dot is created with an even smaller pattern of colored pixels. This means that each dot will have within it multiple pixels of color. Printers use what’s called dithering to create the appearance of more colors than they actually use. The preferred DPI is 300, but you’ll see warnings in Blurb’s BookWright software if you’ve stretched your image to cover too many inches that falls below our standard of 250 DPI for our print projects. This is important because it describes resolution in a way that’s universal and doesn’t vary between devices. You’ll hear “Pixels Per Inch” (PPI) or “Dots Per Inch” (DPI), which is what Blurb uses. In the digital space, pixels indicates size the print space, density. Print pixels (or dots) and digital pixels are different things. All of this interaction-between ink and paper, between colors, between ink and machine, in the tiniest surface area-has an effect on the final look and feel of your physical, printed project.Ĥ. Paper has attributes of its own-surface texture, density, size, color-that interact with ink, changing the way the ink behaves. There’s ink chemistry with pigment and binder, ink temperature, and physical chemistry in how ink and paper interact. Printing is an art form that requires highly technical human expertise. You’re moving from a digital space to a physical one. Through color management we pick the best possible CMYK color to match a given RGB color.ģ. This means that there are often colors on our monitors that cannot be reproduced perfectly in print. Overlay RGB and CMYK color spaces, and you’ll see that colors in RGB that do not have an exact equivalent in CMYK. This conversion will produce unexpected color if not done in a controlled and predictable manner. When a digital image is printed, its RGB numbers are converted to CMYK numbers for the printer. Printing is a subtractive color space because the color we see is reflected light, not the direct light seen when looking at a digital image. Since the total combination of CMYK produces black, CMYK is subtractive color. Most print devices use CMYK to mix and manage colors. This is known as additive color since the total amount of RGB equals white.

We use Red, Green, and Blue (RGB) to describe digital image colors, but we print with Cyan, Magenta, Yellow, and Black ink (CMYK).Įach pixel in a digital image is described by the amount of Red, Green, and Blue light that makes up its color. In the digital world it involves pixel composition. The expression of color in the physical world is about adding or subtracting light. Color reproduction is both art AND science. To get the print to match the capture you created with your camera, you have to align all of these devices to express color data the same way.Ģ. To create a print, you’ll have captured data with a camera, rendered it on a camera screen, then a monitor, and then exported the data to a printer who renders it in ink. But no device translates that digital information into an image exactly the same way. All digital images are captured data that needs rendering. There are multiple devices involved in image production. 5 THINGS TO REMEMBER FOR COLOR MANAGEMENTġ. Most of the time, we’re pleased with how they look, but sometimes it’s not quite right. That’s when it’s helpful to know more about the color management process, so you can troubleshoot.Įven though it’s usually easy, here are some things to keep in mind as you set up your pages. But there’s so much more to it than that! Especially after careful effort to create an image with your camera and editing that has the best reproduction of the moment you experienced, you’ll want to make sure each translation of your image, as it moves across devices from screen to page, is as accurate to your vision as possible. It seems that with one click of a button the images we captured land in our hands. From Screen to Page: Color Management for Perfect PrintingĪs our printing technology has gotten better, it’s easy to take color and color accuracy for granted.
