When to expect your films

Files that are delivered before 2.30 p.m., are often processed and shipped the same day, both with the post as the package service of PostNL, depending on the size.
The films can be sent as express mail or as registered mail. You can check the rates for letters and packages on the site of PostNL. These rates will be charged. During the holidays PostNL uses a custom delivery dates. For more information, visit postnl.nl/feestdagen. Our advice is to send the films during those periods as a package with T&T.

By default, the films are sent in a sturdy envelope by regular mail, without track & trace. Parcel post is sent with track & trace. There are extra charges for the T&T. With parcel post, you will receive an email from shipment@citymail (onlineparcel) with the track & trace code.

We cannot accept any liability for envelopes or packages that are lost or delivered too late by third parties.

Emulsion up or emulsion down? Positive of negative film?

Depending on the used printing techniques there are 4 types of film.

  • Films for offset printing are positive or negative - emulsion side down;
  • Films for screen print are positive - emulsion side up;
  • Films for photopolymer plates (letterpress and flexo) are negative - emulsion side up.

If you need films with emulsion side down or negative films, it's not necessary to deliver your files in this way, our imagesetter ensures the correct settings.

  • Film emulsion side up, the text is readable;
  • Film emulsion side down, the text is in mirror print;
  • Positive: image is black, non-printing areas are transparent;
  • Negative: image is transparent, non-printing areas are black.
positive film, the image area is black, the photosensitive side (emulsion side / print side) is up, so the text is readable
positive film, the image area is black, the photosensitive side (emulsion side / print side) is down, so the text is in mirrorprint
negative film, the image area is transparent, the photosensitive side (emulsion side / print side) is up, so the text is readable
negative film, the image area is transparent, the photosensitive side (emulsion side / print side) is down, so the text is in mirrorprint
At the images above, the emulsion side of the film is located at the front.
The emulsion side is important. The emulsion side of the film should be placed on the emulsion side of the exposed material, to avoid parallax errors during the exposure.
the correct method of exposing film on photosensitive material, film and receiving material are both with the emulsion side side together

Fig. 1 and 2 are based on positive film.
Fig. 1: Correct exposure, emulsion against emulsion.
Fig. 2: Wrong exposure, the light can spread in the base layer of the film, which causes a difference in the image width on the receiving material. Narrower in case of positive film, wider in case of negative film.

Dots per inch

The correct name should be ppi (pixels per inch), but over the years the term dpi is more established. DPI should not be confused with lpi. LPI specifies the lines of dots as grey and colour tones are converted to dots (see "Lpi and images”).
So dpi (dots per inch) indicates the number of points the laser imagesetter will expose on one inch, both horizontally and vertically. By default, our laser imagesetter is set to 2400 dpi. For comparison, a bureau laser printer has a dpi usually between the 600 and 1200 dpi.
Pixelated text, low resolution image equals low output quality
400 dpi
Vector image of text in high resolution equals high output quality
2400 dpi
The higher the dpi, the sharper the image. The image above - highly magnified - displays the output effect of 400 dpi and 2400 dpi. Especially with round or angled forms the jagged pixels, become visible.
DPI is especially important for (scanned) line drawings. A line drawing consists only of black or white and contains no shades. To get a qualitative print, the scanned image should be at least 600 dpi, preferably higher. With 1800-3000 dpi, you get the maximum output quality from our laser image setter. Line drawings scanned on a lower resolution than 2400 dpi will never become 2400 dpi.

Lines per inch

If (black and white) pictures or flat tones are to be printed, the raster image processor of the imagesetter will convert them into a pattern of dots. The lpi value is the number of lines per inch of these dots, also called the line screen.
The basic principles for this conversion are the following:
  • Large dots with a small amount of white in between, represent the dark tones;
  • Small dots, with a large amount of white in between, represent the light tones;
  • Dots with a more or less equal amount of black and white, represent the middle tones;
  • High lpi values equal more detail in the picture;
  • A smooth surface can be printed with a high lpi value;
  • A rough surface must be printed with a low lpi value;
  • Printing on a smooth surface with a too low lpi value may contain insufficient detail;
  • Printing on a rough surface with a too high lpi value can cause the darker shades to clog up.
For photos and flat tones, you need to specify how many lines per inch you want. The correct setting depends on the printing technique and the surface to be printed. Below you will find an overview of the default settings of our imagesetter with the lpi and (rounded) lpcm values.
 45 lines per inch = 18 lines per cm.
 53 lines per inch = 21 lines per cm.
 
65 lines per inch = 26 lines per cm.
 74 lines per inch = 29 lines per cm.
 85 lines per inch = 33 lines per cm.
100 lines per inch = 40 lines per cm.
120 lines per inch = 48 lines per cm.
133 lines per inch = 52 lines per cm.
140 lines per inch = 55 lines per cm.
150 lines per inch = 60 lines per cm.
162 lines per inch = 64 lines per cm.
180 lines per inch = 70 lines per cm.
The lpi values from 45 to 100 are a safe choice for screenprint, letterpress and flexographic printing. The lpi values from 120 to 180 are often used for offset printing. Halftone images are often printed with an angle of 45°. Depending on the printing technique used and the number of colours, this may vary.
In screen printing, the mesh density and the angle at which a mesh is stretched are factors in the choice of a LPI-value and angle. There is a lot of information on the Internet about this, unfortunately this information is not uniform and may require testing for the optimal combination. The general guidelines are:

Mesh = xxx wires/lines per cm. Divide this value by 2.5 or 3.75 (for machine screen printing or 4 or 5 (for manual screen printing) = xxx lines per cm. that will be on the film.
For example: mesh T77 : 2.5 = 31 lines per cm. or 77 : 4 = 19 lines per cm. Multiply the result by 2.54 for the values in inches.

Angles in screen printing

The shape of the dot

By default, our films have the following dot shapes:
  • positiv film, emulsion up: round dot shape
  • positive film, emulsion down: elliptical dot shape
  • negative film, emulsion up: elliptical dot shape
  • negative film, emulsion down: elliptical dot shape
Other dot shapes:
If you need a different dot shape, we ask a small fee for making the right settings and calibration.

You can also dither your files in photoshop. We advise you to make a few tests before you are going to use this technique.
Our Imagesetter is also capable of outputting stochastic fm screens. These frequency modulated screens contain no recognisable pattern. Ask us about the possibilities.

Our file input format is preferably pdf and eps.

For a hassle-free operation please use the following guidelines:

  • When exporting to pdf in Adobe programs, use the default setting PDF/X-1a: 2001. For Adobe Indesign and Adobe Illustrator you can download these job options. For Adobe Photoshop you can use slightly different job options (zip files, please unpack before use);
  • Convert fonts to outlines;
  • No unused colour separations in the file. Please check for the correct colour separation (most of the Adobe programs have a panel for this);
  • Please check your black colour separation (no built up black from cmyk or rgb);
  • When creating pdf files, please check that the compression for line art (monochromatic images) is off;
  • Or choose Bicubic downsampling to 2400 ppi for images larger than 2500 ppi;
  • When using halftone raster images. Please specify the LPI or LPCM (lpi: 2.54 = lpcm);
  • If you need films with emulsion side down or negative films, it’s not necessary to deliver your files in this way, our imagesetter ensures the correct settings;
  • Trim marks, registry marks, colour marks, control strips, etc., must be already in the file.
Other file formats such as CorelDraw and cad-files can also be exposed, contact us about the proper delivery of these files. On this page, you will find more information about the delivery of files.
