Before you submit your meticulously designed artwork for CD or DVD printing, it's crucial to ensure that your images will print in the correct colors. This guide will help you understand the nuances of color formats and how to prepare your files for printing to avoid any unpleasant surprises.
Computer monitors display images using the RGB color model, which stands for Red, Green, and Blue. These colors are combined in various ways to produce a broad spectrum of colors. The absence of light in this model results in black, while the combination of all three colors at full intensity produces white.
Printers, on the other hand, use the CMYK color model, which stands for Cyan, Magenta, Yellow, and Black. This model is subtractive, meaning that colors are created by subtracting varying percentages of light absorbed by the inks. White is achieved by the absence of ink on the white paper, while black is created by combining all four inks.
If you include images in RGB format in your artwork, they may look significantly different when printed. For example, an image of green grass and a blue sky might turn into a brownish autumn scene, completely ruining the summer day image you intended.
When you submit your artwork for printing, the printer's pre-press computers will RIP (Raster Image Process) the file, converting it into a language that the printers can understand. During this process, RGB colors are converted into CMYK colors. Without a proper color profile, this conversion can lead to unexpected results.
To avoid any color discrepancies, convert your images to CMYK before inserting them into your CD or DVD artwork. This can be easily done using software like Adobe Photoshop. If the colors don't look right after conversion, you can adjust them before finalizing your design.
Embedding a color profile in your artwork ensures that the printer knows how to make the conversion from RGB to CMYK accurately. This step is crucial for maintaining color consistency and achieving the desired print quality.
Many CD duplication companies will not accept artwork with RGB images. They aim to ensure that you are satisfied with the final printed product and prefer to address potential color issues upfront. By submitting your artwork in CMYK format, you can avoid delays and ensure a smoother printing process.
Ensuring that your images print in the correct colors involves understanding the differences between RGB and CMYK color models and taking the necessary steps to convert and embed color profiles in your artwork. By doing so, you can avoid unexpected color changes and achieve the high-quality print results you desire.
