Therefore it’s good to ask a manufacturer about additives used, or use natural filament with no added coloring. Even potentially safe filaments might contain unsafe pigments that might be dangerous when in direct contact with food. Unfortunately, it gets more complicated, because we need to take into account the pigments that are used to produce various materials. On the other hand, some materials are rather unsafe and shouldn’t be used for direct food contact – for example, most ABS or ASA filaments. But some filaments should be safe even without any certification, for example, PLA, PETG, or PP. As we mentioned above, you can buy materials with food-grade certification ( PLA by Filaments.ca for example). Let’s take a look at materials that are (not) suitable for direct contact with food. If you need to make food-grade parts for your business, you will be interested mostly in materials with a valid certification. In general, certified materials are more expensive. While there are many materials that are classified as food-grade, there are only a handful of manufacturers who have completed the rigorous and costly certification process. In the USA this issue is covered by the FDA CFR 21 document. 10/2011 that summarizes safe and unsafe materials.

Let’s see why the surface coating is so important, how to add it properly, and what to avoid during the whole process.įirst, let’s talk about regulations: In Europe, there is regulation no. And it’s true, there are several materials that can be considered food-safe, or food-grade to be specific (only certain manufacturers have proper certification), but it’s still necessary to coat the surface to make it truly safe for direct food contact. Be especially careful to keep backgrounds light if there is black or dark colored text over it, so that the text remains readable.You’ve probably noticed that we mention the food-safe properties of some filaments. Generally, you should specify CMYK color builds that look a little lighter than you want, since the dots of ink “fatten up” on press, giving you more pigment on paper than you see on your monitor.
If you do not like the appearance in CMYK, we recommend that you make adjustments while working in CMYK (usually lightening). You may notice a shift in color when converting from RGB to CMYK. By doing it yourself, you have maximum control over the results. We request that you convert your colors from RGB to CMYK if your tools allow you to. Many programs have the capability to convert the layout/images from the RGB color space to the CMYK color space. Therefore, it is physically impossible for the printing press to exactly reproduce colors as we see them on our monitors. The combination of RGB light creates white, while the combination of CMYK inks creates black. These are the inks used on the press in “4-color process printing”, commonly referred to as “full color printing” or “four color printing”. CMYK refers to the primary colors of pigment: Cyan, Magenta, Yellow, and Black. RGB refers to the primary colors of light, Red, Green and Blue, that are used in monitors, television screens, digital cameras and scanners. What is the difference between the RGB and CMYK color space and why does it matter? Also, if you request color correction or other changes after you see your proof, there could be charges for color correction time and a new proof.īottom line: the final product we produce for you is unlikely to match the output from your inkjet – it will look more professional! There can be additional charges for precise color match services. When you approve and return the proof, we will strive to match the color of the proof when printing your final piece. We will produce and send you a hard proof on equipment calibrated to our standard. If you require precise color match, please contact us to arrange for a digital color proof. Due to variation in conditions and equipment, we do not recommend using home or office printers to predict how images or color will render when printed at our facility. Will the colors match a sample I print out on my own printer, or a previously printed sample?Īt Printing For Less we calibrate our equipment to a very rigorous industry standard for ink density and color.
