- Prints are blurry
- the prints were not perpendicular to the sun
- objects or negatives were not in complete contact with the fabric, allowing light to get under the edges
- hazy or cloudy weather - make sure you can see distinct shadows before you begin the process of blueprinting
- Water spots - wet hands or leaves dripping on the fabric before or during exposure
- Brown streaks on back of the print and dark lines on the front - the print was not rinsed well enough. Rerinse immediately.
- Dark blue prints with little or no design visible
- not enough ink on the dark areas of the negative
- exposed for too long
- not rinsed and the print continues to turn blue
- Print very pale
- not enough bright light
- exposure time too short
- No print - make sure the glass does not have UV blocking properties.
Washing And Care Instructions
Cyanoprints are photographs on fabric and can be washed many times as long as you use the correct cleaner. Use only mild, non-phosphate, liquid hand, dish or laundry soaps. Avoid powdered products; they will turn the blue to yellow. Check your product labels and do not use products that contain any of the following ingredients: tri-sodium phosphate (TSP), sodium silicates, washing soda, borax, chlorine, calcium hydroxide (bleach) or hydrogen peroxide. Powdered biodegradable soaps are NOT recommended. If you wish to have something dry cleaned, make sure the cleaner tests swatches using his process. Hand washing is recommended.
