First, let\u2019s define colorfastness simply. In the context of colored tape, colorfastness is the ability of the tape\u2019s ink or color coating to resist fading, bleeding, or transferring when exposed to different conditions: light, heat, moisture, chemicals, or friction. If a tape isn\u2019t colorfast, that bright red you picked might turn pale pink after a week on a shipping pallet sitting in a loading dock, or it might smudge when you wrap a damp box. For businesses that rely on colored tapes for branding (like colored shipping tapes with a company logo) or product labeling, poor colorfastness isn\u2019t just unsightly\u2014it can lead to lost inventory, customer confusion, or even compliance issues if labels become unreadable.<\/p>\n
As someone who\u2019s been supplying tape jumbo rolls for over a decade, I\u2019ve seen firsthand how many manufacturers cut corners on colorfastness to lower costs. They use cheap, low-quality inks that lack UV inhibitors, or apply them thin so they can get the roll on the shelf faster. But that\u2019s a false economy. A customer might save a few cents per roll upfront, but if half their labels fade before the product even reaches the store, they\u2019re wasting way more money reprinting and reapplying. That\u2019s why we prioritize colorfastness in every colored tape jumbo roll we produce\u2014it\u2019s a non-negotiable for both our standard and custom orders.<\/p>\n
Now, let\u2019s get into the key factors that affect colorfastness in colored tape jumbo rolls. Most colored tapes are made with a backing material\u2014usually polypropylene (PP) for general use, vinyl for outdoor applications, or paper for packaging\u2014and a pressure-sensitive adhesive (PSA). The color is either printed as an ink layer on the backing or mixed into the backing material itself. Both methods have their own colorfastness considerations.<\/p>\n
UV exposure is the biggest enemy of color in tape. When ultraviolet light from the sun hits colored ink or pigments, it breaks down the molecular bonds that give the color its hue. This is called photodegradation. For example, a yellow tape roll left outside for a month might turn almost white because the UV rays break down the yellow pigment molecules. That\u2019s why if you need a colored tape for outdoor use\u2014like wrapping furniture for a move, marking construction zones, or securing packages that will be in transit for weeks\u2014you need a tape with UV-stabilized color. In our colored tape jumbo rolls for outdoor use, we add UV inhibitors to both the ink and the backing material to slow down photodegradation. We test these rolls by exposing them to artificial UV light in our quality lab for 1000+ hours, and only release them if they retain at least 90% of their original color (that\u2019s a standard we developed after customer feedback that their old tapes were fading too quickly on loading docks).<\/p>\n
Moisture and humidity are another common threat. If a tape\u2019s ink isn\u2019t moisture-resistant, it can bleed when exposed to rain, condensation, or even high humidity in a warehouse. I once had a customer in the food packaging industry tell me that their old tape would smudge when they wrapped fresh produce, leaving unreadable labels that led to mispricing. That\u2019s because their tape\u2019s ink was water-based and not sealed properly. For applications where moisture is a factor\u2014like shipping to humid climates, frozen food packaging, or marine use\u2014we use solvent-based, waterproof inks that form a durable barrier on the backing. We also do a bleed test for every batch: we dip a sample of the colored tape jumbo roll in room-temperature water for 24 hours, and check if any color transfers to a white paper towel. If it does, the batch gets rejected.<\/p>\n
Heat is another factor. High temperatures can soften the adhesive, but they can also break down color pigments. For example, a tape used to seal packages in a truck that\u2019s parked in the desert can get up to 140\u00b0F (60\u00b0C) inside. If the color isn\u2019t heat-resistant, it can fade or even discolor. We test our colored tapes at extreme temperatures to make sure. For high-heat applications, we use heat-stable pigments that don\u2019t break down below 200\u00b0F (93\u00b0C), so even in a hot truck, the color stays intact. For cold storage applications, we also test at -20\u00b0F (-29\u00b0C) to make sure the color doesn\u2019t turn dull when the tape is exposed to freezing temperatures.<\/p>\n
Friction and abrasion might seem less obvious, but they matter too. If a tape is used to wrap heavy boxes that will be stacked on top of each other, the color can scratch off if it\u2019s not durable. That\u2019s especially true for custom printed tape, where a company\u2019s logo is part of the design. We use a clear overcoat on top of the ink layer for most of our colored tape jumbo rolls, which acts as a shield against scratches and rubbing. We also test abrasion resistance by rubbing the tape back and forth with a standard weight for 100 cycles, and checking if any color comes off on a white cloth. For heavy-duty industrial tapes, we upgrade to a thicker overcoat to handle more rough handling.<\/p>\n
Now, let\u2019s talk about the different types of colorfastness ratings you might see when shopping for colored tape jumbo rolls. It\u2019s important to understand these ratings so you don\u2019t get misled by marketing claims. The most common ratings are the International Organization for Standardization (ISO) ratings, specifically ISO 105-B02 for light colorfastness and ISO 105-E01 for water colorfastness. ISO 105-B02 rates colorfastness on a scale of 1 to 8, with 1 being the worst (fades almost immediately) and 8 being the best (resists UV exposure for years). For our general-purpose colored tapes, we aim for a rating of 4 to 5, which is good for indoor use. For our outdoor and heavy-duty tapes, we go up to a 6 to 7, which is suitable for prolonged outdoor exposure.<\/p>\n
A lot of suppliers will claim their tape is \u201ccolorfast,\u201d but they don\u2019t specify the rating. That\u2019s a red flag. A tape with a 4 rating might be fine for a label that stays in a closet, but it will fade in a week outside. When we provide samples to potential customers, we always include the colorfastness test results so they know exactly what they\u2019re getting. We also make it clear which tapes are for indoor use, which are for outdoor, and which are for specific conditions like high humidity or heat.<\/p>\n
Another common question we get: is mixing color into the backing better than printing it on top? For some applications, yes. If the color is part of the backing material itself, it doesn\u2019t have an ink layer that can bleed or scratch off. That\u2019s why clear vinyl tapes, for example, might have color mixed into the vinyl during manufacturing, instead of printed on the surface. This method has excellent colorfastness because the pigment is inside the material, not just on top. But it\u2019s more limited in color options\u2014you can\u2019t get custom bright logos as easily with bulk color mixing, since it requires changing the entire batch of backing material. For custom printed tapes, printing on top of the backing with a durable ink is still the best option, as long as you use the right ink and overcoat.<\/p>\n
We\u2019ve had customers switch to our colored tape jumbo rolls from cheaper brands, and the feedback is always about colorfastness. One customer who runs a e-commerce business told me that before, their shipping tapes would fade by the time the package was delivered to a customer in Arizona. Now, with our outdoor-grade colored tape, 99% of the tapes arrive intact and bright, which means customers can easily read the address and the brand logo stands out. That\u2019s the kind of difference colorfastness makes. It\u2019s not just about aesthetics\u2014it\u2019s about functionality, brand consistency, and customer experience.<\/p>\n
Of course, no tape is 100% colorfast forever. Even the best tapes will eventually fade if exposed to extreme conditions for a very long time. But the goal is to match the tape\u2019s colorfastness to its intended use. If you\u2019re using tape to label boxes that will sit in a climate-controlled warehouse, you don\u2019t need the same high UV resistance as a tape that will be on a roof for a year. That\u2019s why working with a supplier who understands your specific needs is key. As a tape jumbo roll supplier, we don\u2019t just sell rolls\u2014we help customers choose the right tape for their application, including the right level of colorfastness.<\/p>\n
