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
We can write masks at 4 different resolutions, called "dpi" (dots per inch which refers to addressability, not optical resolutions. The higher the resolution, the better the quality. For each increase in DPI, there will be a 2x improvement in the following parameters: Addressability, Minimum Line, Edge Roughness, CD Uniformity.
4k DPI : LOW Resolution. Although this resolution may resolve smaller features, we recommend keeping feature sizes above 75um as corner rounding is considerable. Edge sharpness and definition is acceptable for non critical design types, although designs with arcs/circles and lines running off 90 degree grid may show pixilation. NO features such as lines / circles / spots / squares below 60 um unless on a 'best effort' basis previously agreed with our technicians.
10k DPI : MEDIUM Resolution. This resolution will usually resolve down to 48 micron lines with decent line edge qualities with only a slight pixilation along edges. Corner rounding is still noticeable under magnification. NO features such as lines / circles / spots / squares below 40um unless on a 'best effort' basis previously agreed with our technicians.
16k DPI : HIGH Resolution.It offers an excellent price/quality balance. This resolution will resolve down to 24-micron lines and has very good line edge qualities with little pixelation along edges, although some circles/squares and spots may have some distortion to them. Corner rounding is usually acceptable at this level.
20k DPI : PREMIER Resolution.It is excellent for demanding, high-precision photomasks, and is the best quality that we can offer. This resolution will resolve down to16 micron lines (depending on the geometry type ) and has good line edge qualities with little pixelation along edges, and corner rounding is only noticeable under high magnification. Note that where feature sizes are required below 16um, it may be possible given increased setup costs.
CAD FORMAT
We can accept various formats of data. Whilst Gerber remains the most common for the PCB and electronics Industries, we also have the ability to image from postscript, graphics files and Adobe Illustrator for our customers based more in the Graphics Industries. And, fo course, common CAD formats such as DXF, GDSii can also be manipulated. These data formats listed above are only a small section of what is available - please contact us for further information and clarification. We are also able to provide a full drafting service whereby we can create your designs from drawings and descriptions.
PRODUCTION SCHEDULE
Standard leadtimes from receipt of data to shipping are 3 days, but where orders are very urgent and prompt delivery is critical to a projects success - you can count on us to deliver by offering a sameday service - from receipt of order to shipping of films in the same production day ! The offer of this service is dependant on current production workloads and all orders must be complete and submitted by 10.00am

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.
