The Graphtec FC8600, a workhorse in the signage and graphics industry, can reliably cut reflective film up to approximately 15 mils (0.015 inches or 0.38mm). Exceeding this thickness can compromise cut quality, blade longevity, and even potentially damage the plotter.
Understanding Reflective Film and the FC8600’s Capabilities
Reflective film, commonly used for road signs, vehicle graphics, and safety markings, presents a unique challenge to cutting plotters. Its composition often includes a layer of embedded glass beads or microscopic prisms that provide the reflectivity, increasing its rigidity and thickness compared to standard vinyl. The Graphtec FC8600, known for its power and precision, is capable of handling a range of materials, but understanding its limitations regarding reflective film thickness is crucial for optimal performance and longevity.
The stated 15 mil maximum is a general guideline. Actual achievable thickness can be influenced by several factors, including the specific brand and type of reflective film, the condition of the blade, the cutting force settings, and the complexity of the design. It’s always recommended to perform test cuts on scrap material to determine the optimal settings before embarking on a full production run. Overly thick film can prematurely dull the blade, leading to ragged edges and inconsistent cuts. It also places excessive stress on the plotter’s motor and mechanics, potentially shortening its lifespan.
Factors Influencing Cutting Performance
The FC8600’s ability to cut reflective film effectively hinges on several interacting parameters. Ignoring these factors can lead to frustrating results and potential damage to your equipment.
Blade Sharpness and Type
The type of blade used is paramount. A specialized blade designed for thicker materials with a steeper angle is generally recommended for reflective films. Regular inspection and replacement of the blade are vital. A dull blade requires more force to cut, increasing the risk of tearing the film or damaging the cutting strip.
Cutting Force and Speed
Finding the right balance between cutting force and speed is essential. Insufficient force will result in incomplete cuts, while excessive force can damage the film or the cutting strip. Lowering the cutting speed can sometimes compensate for increased thickness, allowing the blade more time to penetrate the material.
Downforce Adjustment
The Graphtec FC8600 provides precise downforce adjustment. This setting controls the pressure exerted by the blade onto the film. Calibrating the downforce correctly is crucial for achieving clean cuts without damaging the material or the plotter.
Test Cuts and Material Calibration
Before committing to a large project, always perform test cuts on a small piece of the reflective film. This allows you to fine-tune the cutting parameters and ensure optimal results. Graphtec’s software often includes material calibration features that can help determine the ideal settings.
Best Practices for Cutting Reflective Film
Following these best practices will help ensure consistent, high-quality cuts and prolong the life of your Graphtec FC8600.
Regular Maintenance
Regular maintenance of the plotter is crucial. This includes cleaning the cutting strip, lubricating moving parts, and keeping the machine free from dust and debris.
Proper Material Handling
Ensure the reflective film is properly loaded and aligned on the plotter. Wrinkles or misalignments can negatively impact cutting accuracy.
Software Settings
Utilize the appropriate software settings for cutting reflective film. This may involve adjusting the cutting force, speed, and offset.
Monitor Blade Wear
Monitor blade wear and replace the blade when it becomes dull. Using a dull blade can damage the film and the plotter.
FAQs: Demystifying Reflective Film Cutting with the Graphtec FC8600
Here are some frequently asked questions to further clarify the process of cutting reflective film on the Graphtec FC8600.
FAQ 1: Can I cut thicker reflective film by making multiple passes?
While multiple passes might seem like a solution for thicker films, it’s generally not recommended. It can lead to registration issues, where the blade doesn’t follow the exact same path on each pass, resulting in a jagged or uneven cut. Focus on selecting a film within the recommended thickness range.
FAQ 2: What type of blade is best for cutting reflective film on the FC8600?
A blade specifically designed for thicker materials, often with a steeper cutting angle (e.g., 60-degree or even 75-degree), is generally recommended. Consult your blade supplier for recommendations based on the specific type of reflective film you are using. Graphtec also offers blades designed for specific materials.
FAQ 3: How do I know if my blade is dull?
Signs of a dull blade include ragged or uneven cuts, difficulty weeding the material, and the need for significantly increased cutting force. Inspect the blade under magnification for any signs of chipping or wear.
FAQ 4: What cutting force settings should I use for reflective film?
There is no universal answer. The ideal cutting force depends on the film’s thickness and composition. Start with a low force and gradually increase it until you achieve a clean cut without cutting through the backing material. Test cuts are crucial.
FAQ 5: Can I use the FC8600 to cut prismatic reflective film?
Prismatic reflective film, which uses larger prisms for higher reflectivity, is often thicker and more rigid than standard glass bead reflective film. While the FC8600 might handle thinner prismatic films, it’s essential to stay within the 15 mil limit and perform extensive testing. Heavier-duty cutting equipment might be required for thicker prismatic materials.
FAQ 6: What is the best way to weed reflective film after cutting?
Weeding reflective film can be challenging due to its adhesive properties and tendency to tear. Use a sharp weeding tool and work slowly and carefully. Applying a small amount of heat from a heat gun can sometimes soften the adhesive and make weeding easier, but use caution to avoid damaging the film.
FAQ 7: How does the cutting strip affect cutting performance?
A worn or damaged cutting strip can negatively impact cutting performance by providing inconsistent support for the film. Replace the cutting strip regularly to ensure optimal cutting quality.
FAQ 8: What maintenance procedures are important for the FC8600?
Regular cleaning of the plotter, lubrication of moving parts, and inspection of the cutting strip and blade are essential. Consult the Graphtec FC8600 user manual for detailed maintenance instructions.
FAQ 9: What software settings should I adjust besides cutting force and speed?
Blade offset is another crucial setting. This compensates for the distance between the blade tip and the center of the blade holder. Adjusting the offset correctly ensures that corners are cut cleanly and accurately.
FAQ 10: Can I use a felt squeegee on reflective film during application?
It is generally recommended to use a felt squeegee with a soft edge on reflective film. Metal or hard plastic squeegees can scratch the reflective surface. Use firm, even pressure to avoid trapping air bubbles.
FAQ 11: How do temperature and humidity affect reflective film cutting?
Extreme temperature and humidity can affect the adhesive properties of the film and potentially cause it to warp or shrink. It is recommended to cut reflective film in a controlled environment with stable temperature and humidity levels.
FAQ 12: What should I do if the reflective film is tearing during cutting?
If the film is tearing, first check the blade sharpness. A dull blade is a common culprit. Reduce the cutting force and speed, and ensure the film is properly supported by the cutting strip. If the problem persists, consider using a different type of reflective film or a different cutting plotter.
