Perforated Window Decals

As per printing standards, we print in CMYK. 

Yes, a QR code can still work and be scanned when included on a perforated wall decal, but there are a few factors to consider to ensure it scans effectively:

Factors to Ensure QR Code Scans Well:

1. Size and Placement:

   • Size: Make sure the QR code is large enough to be scanned easily. QR codes should be printed at a size where the individual squares are easily distinguishable by a scanner.
   • Placement: Position the QR code in an area of the decal where it is visible and not obscured by the perforations. Ideally, place it in a section with fewer or no perforations.

2. Design and Contrast:

   • Contrast: Ensure there is sufficient contrast between the QR code and the background. A high contrast (e.g., black code on a white or light-colored background) helps scanners read the code more effectively.
   • Design: Avoid placing the QR code in areas with heavy patterns or colors that might interfere with its readability.

3. Perforation Considerations:

   • Perforation Size: The size and density of the perforations can impact the ability of a QR code to be scanned. Larger and fewer perforations may be less problematic, while very small or dense perforations could interfere with the scanner’s ability to read the code.
   • Code Integrity: Ensure that the perforations do not cut through the QR code or disrupt its pattern. The integrity of the code’s squares is crucial for accurate scanning.

4. Testing:

   • Pre-Print Test: Before finalizing the decal, test the QR code on a sample or mock-up to ensure it scans properly through the perforations.
   • Scanning in Different Conditions: Test the QR code with various devices and under different lighting conditions to ensure it remains scannable.

By considering these factors and testing the QR code before full production, you can ensure that your perforated wall decal with a QR code will be effective and easy to scan.

Removing an old perforated window decal and applying a new one requires some care to avoid damaging the glass. Here’s how you can do it:

Removing the Old Perforated Window Decal:

1. Heat the Decal:

   • Use a hairdryer or a heat gun on a low setting to warm up the decal. Move the heat source back and forth over the decal to loosen the adhesive.
   • Be careful not to overheat the glass, as this could cause damage.

2. Peel Off the Decal:

   • Start at one corner of the decal and slowly peel it off using your fingers or a plastic scraper.
   • Pull at a low angle, close to the glass, to minimize tearing.

3. Remove Adhesive Residue:

   • If any adhesive remains, use a solvent like rubbing alcohol, window cleaner, or a commercial adhesive remover.
   • Apply the solvent to a soft cloth and gently rub the adhesive until it dissolves.
   • For stubborn residue, let the solvent sit for a few minutes before wiping.

4. Clean the Glass:

   • Thoroughly clean the glass with a glass cleaner to remove any leftover residue or dirt.
   • Ensure the surface is completely dry before applying the new decal.

Applying the New Perforated Window Decal:

1. Measure and Cut (if needed):

   • Measure the window to ensure the decal fits properly. If necessary, trim the decal to the correct size using a sharp utility knife and a straight edge.

2. Prepare the Surface:

   • Clean the window again to ensure it’s free from dust and debris.
   • For best results, apply the decal in a dust-free environment.

3. Position the Decal:

   • Peel off a small section of the backing paper and align the decal on the window.
   • Once aligned, slowly remove the backing paper while pressing the decal onto the glass.

4. Apply the Decal:

   • Use a squeegee or a credit card wrapped in a soft cloth to smooth out the decal, working from the center outward to remove any air bubbles.
   • Apply even pressure to ensure good adhesion.

5. Trim Excess (if needed):

   • After the decal is applied, use a sharp utility knife to trim any excess material along the edges.

6. Let it Set:

   • Allow the decal to sit for a few hours (or as recommended by the manufacturer) to ensure the adhesive fully bonds with the glass.

Following these steps should help you successfully remove the old decal and apply a new one.

Perforated window decals can act as a shade to some extent. These decals have tiny holes that allow for one-way visibility, meaning you can see out, but people outside have a harder time seeing in. They provide some level of sun blockage, reducing glare and filtering out a portion of the sunlight. However, they don't block out the sun as effectively as dedicated sun shades or blinds. The level of shade provided depends on the density of the perforation and the material of the decal.

Perforated decals can be placed or installed both indoor and outdoor, and they may be affixed to a plexiglass office window

Our perforated window decals are easy to install. You may click the link below to download a copy of the instructions:

INSTALLATION INSTRUCTIONS

Perforated window decals are typically designed for one-time use and are not intended to be removed and reused. When applied to a surface, the adhesive on the back of the decal adheres to the window, and attempting to remove it usually results in damage to the decal or difficulty in reapplying it due to the nature of the material and adhesive.

While there might be some cases where it's possible to carefully remove a perforated window decal and reapply it elsewhere, it's not recommended. The perforations in the material and the adhesive properties are usually optimized for a single application, and attempting to reuse the decal could lead to issues such as reduced adhesion, damage to the decal, or an uneven appearance when reapplied.

If you need a decal that can be removed and reused multiple times, you may want to consider alternative options such as static cling decals or removable vinyl decals, which are designed specifically for multiple applications and removals without damaging surfaces or losing their adhesive properties.

Our perforated decals are 50/50 micro-perforated, meaning 50% of your decal consists of solid vinyl material, while the other 50% features micro punctures. This design allows one side of the graphic to appear opaque and the other side to appear see-through.
