All standard resolution photoplotted films are imaged and processed using a fully automated system operating continuously. This minimizes manual handling, improves quality, and supports high-volume production.
Laser photoplotted films are suitable for PCB phototools, photo etch film tools, photoresist exposure masks, and various graphics applications.
BASE MATERIAL
All films are produced using Agfa Idealine HPF (High Resolution Plotter Film), a 0.18 mm polyester film with a single-sided photographic emulsion. Designed for precision imaging, films are processed in controlled environments to ensure dimensional stability. For best results, store and handle films at 21 °C and 50% relative humidity.
RESOLUTIONS
Films are available in two imaging resolutions (“dpi”). Higher resolution improves feature quality. See the SPECIFICATIONS section for resolution-dependent tolerances and dimensional accuracy.
4k dpi: LOW Resolution. Suitable for general-purpose applications such as screen printing, tab printing, and photoetching. While capable of imaging smaller features, features below 0.2 mm may exhibit significant corner rounding. Designs with arcs or off-grid elements may show pixelation. Features below 0.1 mm are not supported unless pre-approved on a ‘best effort’ basis.
10k dpi: MEDIUM Resolution. Provides improved line quality, with typical resolution down to 0.1 mm. Corner rounding is reduced but still present under magnification. Features below 0.08 mm require prior approval and are provided only on a ‘best effort’ basis.
CAD FORMAT
Only commonly used file formats are listed. If your format is not shown, contact us for confirmation. A full drafting service is available for converting drawings or specifications into production-ready designs.
PRODUCTION SCHEDULE
Standard lead time is 24 hours from receipt of data to shipment. For urgent requirements, same-day production and dispatch may be available. Please notify us as early as possible if this service is needed so we can allocate production time accordingly.

POLARITY Films are available as Clearfield (positive) or Darkfield (negative). In positive polarity, CAD features appear as emulsion on a clear polyester background. In negative polarity, the features are clear, and the background is emulsion. Include a reference text in your design to indicate film orientation, and specify if it should appear right-reading or wrong-reading as viewed on screen. |
CERTIFICATION
All photomasks are subject to a rigorous inspection process, regardless of the selected inspection class. Critical parameters such as CD (Critical Dimension) size and uniformity are measured and recorded internally. High-magnification images are captured using Nikon MM40 (900×) and OGP ZIP 300 (400×) systems, and stored with our production records. In some industries—particularly medical or automotive—additional inspection documentation may be required for compliance with quality systems. You can select the level of documentation to be provided with your order.
None: Full inspection performed; no documentation issued.
Certificate of Conformance: Printed certificate confirming compliance with inspection criteria.
Certificate of Measurement: Verifies up to 10 user-defined dimensions against specified tolerances. A CAD file or drawing must be provided indicating the positions to be measured. Additional measurements available on request.
CHECKPLOT
Before production, we supply a checkplot—an essential part of our approval workflow. This checkplot is a high resolution PDF graphic, emailed to you for review. It provides an overview of the design layout, helping you confirm pattern alignment, feature placement, and polarity. However, it is a rasterised image and not suitable for verifying precise dimensions.
For critical designs where dimensional accuracy must be confirmed at the CAD level, we recommend using our online CAD checkplot viewer. This platform allows you to inspect your design using vector data, ensuring that features such as linewidth and spacing match your expectations. You can zoom in to inspect fine details, toggle layers, and therefore compare your submitted file against our interpreted version.
Checkplot approval is mandatory before manufacturing begins. No production will start until confirmation is received. Ensure that your review includes polarity, reading direction, and any reference markers required by your process.
For more details, see our Checkplot Information Page.
YOUR DRAWING NUMBER
Include the CAD filename or drawing number with your order to ensure correct data matching.

| FAQ | FAQ's
Q: What does the term NEGATIVE and POSITIVE mean ? A: Polarity is the tone of the pattern. When you draw your design, polarity determines whether the features on the film are CLEAR or BLACK on the final film. So, a NEGATIVE film would have the items you have drawn in CAD as CLEAR on the film. Obviously this is the opposite for POSITIVE, where the items you drawin CAD are BLACK on the film.
Q: I've designed my pattern with the wrong polarity - what do i do ? A: We can use the original design file and simply reverse the tone of the film. This is much easier than supplying new data.
Q: How accurate are the features? What tolerances do you work to? A: Accuracy is determined by the imaging resolution. Click here to refer to the Technical/Resolutions/Photoplotting menu on our website for a chart detailing both feature and dimensional tolerances.
Q: What resolution should I choose? A: Higher resolutions yield sharper feature edges, finer minimum features, improved accuracy, cleaner corners, and smoother curves. The importance of these factors varies by application. If uncertain, select a higher resolution to meet critical requirements. We can advise further if you send us your design.
