Prepress Services in Brisbane
About the Product
Pre-Press Film is produced through a photographic process where light sensitive film is exposed to light in precise manner and processed using film developer and film fixer, again in precise manner, to achieve Dense (silver based) Blacks with very sharp edges.
Blacks typically have density >2.0 resulting in predictable printing plates and screens as there are no greys. Such density allows a wide over-exposure tolerance and traditional Bleed, Choke, Dot Gain, and Dot loss methods using spacer foils. These are techniques which cannot be done with toner or inkjet produced acetates, or transparencies, as they cannot achieve such densities, accuracy or stability.
Film exposure is by laser imagesetter (Screen Katana) with a maximum image area of 1100 x 550mm. Results are predictable, repeatable, and accurate (measured to +/- 1/100th mm on the laser axis)
Separations and Halftone dots are an inherent part of the film making process and you can specify the dot shape, frequency, and dot angle or angle offset to suit your application. If you are unsure, we have standard angle sets and Dot types that we have selected as most suitable for each different print process and they are most likely perfect for your needs as is, off the shelf. We have been doing this since the early 1980’s so we have got a pretty good idea of what you need. We’ve have had plenty of practice and you can be sure that we know what we are doing and your film will do the job you want it to.
Films can be stored indefinitely without loss of density and dimensional stability.
Our Lithographic, Screen Printing, and Letterpress films are priced as follows:
- A4 = $ 20.00 +gst
- A3 = $ 26.00 +gst
- A2 = $ 50.00 +gst
- 540x850mm = $ 70.00 +gst
- 540x x1100mm = $ 95.00 +gst
Size relates to the required image, any extra used for printers marks added to the image are included free.
Colour separations require one film per colour.
Files should be supplied as print ready pdf.
We do have the ability to handle any sort of file format, but other file types may incur operator charges as they are not designed to be portable and almost inevitably need operator intervention.
Please include film specifications with your order
If you don’t know, that’s fine, just tell us about what you want to do with the films and we can work it out for you.
But if you do know: don’t make us guess, please advise:
- Type: Positive or negative,
- Emulsion side: Litho or Screen emulsion
- Frequency: aka “Screen ruling” in LPI (Lines per inch)
- Dot Shape: Round, Square, Euclidean, Diamond, Stochastic.
- Angles: Standard angle set is: cmyk -15/75/0/45 degrees
- Offset: an offset is applied to each angle usually to find a best fit to screen mesh
When specifications are not supplied, our default screen rulings are 150# for litho and 55# for Screen printing.
Our default angle offset, dot shape, and angle sets, are standards that we are sure will work for the specified film type, but you are welcome to select your own.
Imposition, re-sizing, manual trapping, colour bars, and any other operator intervention, is work additional to the film production process and is charged at an hourly rate.
Production time is generally next day
but please advise if you have specific time needs.
Our standard courier supplier is “Fastway” or “Couriers Please”.
We are happy to organize alternate delivery via “receiver pay” systems, but there will be minor packaging/handling fee.
You are welcome to collect your film.
We have car parks available on Campbell street and our Jeays Street hardstand.
We guarantee the quality of our product.
