F.O.P. (Front of Package) Food Labelling
Canada’s mandatory FOP “High in” symbol applies to many foods by Jan 1, 2026. Clients must confirm requirements with Health Canada and supply compliant artwork.
Outlining Fonts
Outline fonts in Illustrator to turn text into vector shapes so it prints exactly as designed—no font substitutions. Save one outlined copy and one editable copy (or send the font files with your artwork).
Creating a White Layer (for Clear or Polychrome Materials)
A white ink layer is required on clear or metallic materials so your colours print opaque and vibrant. Create a “Spot White” layer in Illustrator (spot swatch + overprint) to define where white ink will print.
What are Barcodes and How do they Work?
GS1 barcodes are required by most retailers to sell and track products. The bars are machine-readable, and the UPC numbers are human-readable—leave proper quiet zones for reliable scanning.
CMYK vs. Pantone vs. RGB
RGB is for screens; CMYK is for printing. Convert RGB files to CMYK to avoid color shifts. Pantone (PMS) offers precise spot colours for branding but is mainly for flexographic or offset printing.
PRX Print Artwork File Guidelines/Checklist
We require print-ready high-res PDF or EPS files. To avoid delays, outline fonts, embed 300ppi images, use CMYK, and add 1/16” bleed. Files failing these specs may incur additional art fees.
FAQs
What is Augmented Reality?
Augmented Reality (AR) labels allow customers to scan a label with a mobile app to trigger a virtual experience, such as video instructions, contests, or “live” information. It helps differentiate products and provides data analytics on user engagement.
What are QR Codes?
QR (Quick Response) codes are scannable codes that link smartphone users directly to the online world, such as product features, benefits, promotions, or surveys.
What Are Barcodes and How Do I Get Them?
Barcodes (UPC symbols) track inventory and sales. Large retailers require them. To get them, you generally need to contact GS1 (http://www.gs1ca.org) to obtain unique product codes. PRX Print helps with the design placement and printing of barcodes to ensure they are compliant and scannable.
What are Flipover Labels?
FLIPOVER! labels allow for full-color printing on the back of the label. This provides extra space for instructions, recipes, safety data, or multi-language information without covering up the product or increasing material costs.
What Type of Adhesive Should I Use?
-
Cold/Freezer Temperature: Adheres to refrigerated or frozen substrates (generally +35 F or colder).
-
Permanent: Standard to High adhesion – cannot be removed easily. Ideal for warehouse carton labelling and labelling any product that is at room temperature.
- Extra Aggressive: a very strong, more tacky and durable adhesive designed for racking, outdoor, and hard-to-label applications. High adhesive, difficult to remove.
-
Removable: Low adhesion; removes without leaving residue (though may become permanent over time/weather exposure).
-
Textile: Removes cleanly from fabric (not for velvet, fur, suede, or leather). Ideal for clothing returns.
-
Ultra Removable/Repositionable: Can be reapplied multiple times without gaining permanency. Great for glass/windows.
Should I print my labels in house or outsource to a label company?
If your design is simple, materials are standard, and quantities are low, in-house printing is an option. However, you should outsource if:
-
Your labels are complex (special shapes, sizes, foils, textures).
-
You require special adhesives (cold temp, moisture resistance).
-
Your product requires a high-end look to compete with major retailers.
-
You cannot keep up with demand or equipment maintenance costs.
Why is my label not sticking?
There can be several reasons. To ensure adhesion:
-
Check that the adhesive is the correct type for the application temperature (e.g., cold temp/freezer adhesive for frozen environments).
-
Ensure the surface is clean and free of oily or waxy residue.
-
For small, unusual, or textured containers, use a slight overlap to prevent edges from lifting. Sometimes shrinksleeve labels are a better solution for specific containers.
What Makes a Label Waterproof?
Waterproof labels are constructed with a synthetic facestock (such as polypropylene or polyethylene) or vinyl, rather than wood fibers like paper. PRX Print uses a heat-based toner to fuse ink directly into substrates so it never runs, and offers protective varnishes (gloss or matte) and overlams for protection against chemicals and oils. Adhesive choice is also critical and depends on the surface tension and application environment.
When do I Need Waterproof Labels?
Waterproof/water-resistant labels are essential or chosen in many applications where durability is important, where brand or safety information cannot be compromised, or to simply add attraction to packaging.
-
Food and Beverage Packaging: For items like wine, beer, or refrigerated dips where moisture can cause paper labels to peel or look soggy.
-
Health and Beauty Products: For items used in bathrooms (shampoos, soaps, creams) where steam and water can damage labels.
-
Products That Are Handled/Stored Roughly: For items stored outdoors or handled by machinery/forklifts where durability against the elements and tearing is required.
