Ink notes
Photo Angles
A practical press-floor note on taking useful press photos that show print defects, anilox condition and substrate problems properly.
A useful press photo is more than proof that a job ran. Photo Angles explains which shots help on a flexo floor, from plate mounting and doctor blades to print defects on film or board.
Good fault photos need intention, not a rushed snap beside the unit. On flexo work in Gauteng, KwaZulu-Natal and the Western Cape, glare from guards, poor flash use and dirty lenses often hide the very mark that needs checking.
Shots that identify the defect
- Wide shot of press side and unit
- Close photo of the defect area only
- Plate or ink reference shown clearly
- Operator name, plant and shift noted
When the print sample looks different from what the eye saw on press, the photo set needs to show where the difference starts. A useful set usually includes one overall view, one mid-range setup shot, and a close image that shows dots, scumming, chatter or substrate damage. That combination helps separate a print issue from a lighting problem in the photo itself.
Angles for anilox and plates
Photo Angles shows how to take press photos that are actually useful when a fault needs checking. Good images should clearly show the defect, the plate or anilox condition, and the substrate surface without glare hiding the problem.
Start with light direction before you touch zoom. In Johannesburg plants, overhead LEDs can wash out faint banding, while coastal humidity around Durban may leave a haze on guards that reflects straight back into the lens. Tilt the phone slightly off square when photographing anilox cells, mounted plates and doctor blade contact so the surface texture stays visible.
One image taken before wash-up matters more than ten after the line is stripped. Keep a first-off sample, then photograph the plate edge, web path and the marked defect location while the settings are still unchanged. That record is far more useful when a repeat fault appears on the next run.
What a usable image set shows
A strong press photo set names the substrate, colour station and fault position on the web. It also shows whether the mark repeats at a plate length, follows an anilox issue, or sits with wrinkles, dirt or static on film. Those clues matter when film, linerboard and coated stocks behave differently under the same light.
Before sending images, compare this note with related fault checks under Ink notes and the setup sequence in Press paths. Include one wide press view, one close shot of the defect, and one photo of the component under review such as the plate, doctor blade chamber or anilox.
- Defect position marked on the web
- First-off sample photographed before adjustments
- Lighting source noted with each photo
South African lighting and dust issues
Many local plants work under mixed light from skylights, sodium fittings and newer LEDs, which can shift how ink density appears in a phone image. Dust inland can settle on guards and lenses, while coastal salt air can leave a film that softens detail on metal surfaces. Note the site and conditions so a faint haze in the picture is not mistaken for a press defect.
Load-shedding and restart conditions can also change what a photo needs to prove. After a stop, take one image of the web path, one of the first stable print, and another of any register or impression adjustment that followed. That sequence gives context when comparing samples from Cape Town, Durban or the Highveld.

Before you photograph the run
A practical press-floor note on taking useful press photos that show print defects, anilox condition and substrate problems properly.
Wipe the lens, hold the sample flat, and switch off beauty filters or automatic effects. Put a pen, rule or finger near the mark for scale only if it does not cover the defect. If flash causes hot spots on film, move the angle first rather than stepping further away.
