DIN 33870
Die DIN 33870 vom Januar 2001 legt die Standards für Beschaffenheit, Lagerung, Verpackung und Kennzeichnung von Tonerkartuschen fest.
Sie sagt auch aus, mit welcher Flächendeckung/Schwärzungsgrad/Helligkeit die Seitenleistung angegeben werden muss. Die Deckung soll demnach 5% betragen.
Zudem müssen die Tonerkartuschen einem „Armes Test“ unterzogen werden. Dieser ist ein bakterielles Prüfverfahren auf erbgutverändernde Eigenschaften von Stoffen. Weiterhin werden Tests auf Ergiebigkeit und in Klimakammern durchgeführt. Untersucht werden müssen auch die Darstellung der Inhaltsstoffe und Sicherheitshinweise.
Selbst die Verpackung wird auf Umweltverträglichkeit hin untersucht. Die Lagerung wird in der DIN 33870 nach Luftfeuchtigkeit und Temperatur normiert.
Die DIN 33870 gilt auch für wiederaufbereitete (rebuilt) Tonermodule. Jedoch dürfen gebrauchte Einheit maximal vier mal wiederverwendet werden, wenn sie der Norm genügen sollen.
Es sind folgende durchzuführende Arbeitsschritte spezifiziert:
- Komplette Demontage
- Reinigung
- Austausch von Verschleißteilen
- Wiederbefüllung
RebuiltToner, die nach der DIN 33870 geprüft wurden entsprechen der Qualität von Originalmedien und sind daher vorbehaltlos zu empfehlen, da sie zudem im Preis um bis zu 60% günstiger sind.
Octopus Write & Draw Ink, waterproof ink for fountain pen, nib and brush, vegan
The Octopus Write & Draw inks are unique, smudge-proof and waterproof writing and drawing inks in a wide range of colours. They were developed for daily use in fountain pens and are also popular with graphic artists, illustrators, calligraphers and artists for writing, sketching, drawing and colouring with calligraphy pens, glass pens or brushes.
Each of the 38 brilliant shades inspires with its intense colour power thanks to its high, balanced pigmentation. In addition to a deep black and various shades of grey, the extensive colour palette also includes a particularly opaque white, which can be used on dark backgrounds.
During the development of the drawing ink, special attention was paid to its use in the fountain pen. The use of the finest colour pigments in a carefully balanced formula ensures high light fastness and a good, even ink flow without clogging the ink duct of the fountain pen. These pigmented writing inks also feature the excellent writing behaviour of the classic Octopus fountain pen inks. The Write & Draw drawing ink meets the requirements for document-proof ink according to DIN ISO 12757-2 and DIN ISO 14145-2 and is produced exclusively with vegan ingredients.
Writing enthusiasts love the razor-sharp typeface that can be achieved on fountain pen-suitable paper and the pleasant shading of the Write & Draw writing ink. Calligraphers can create the finest hairlines and impressive flourishing elements, while urban sketchers can draw precise outlines.
The ink dries waterproof in a very short time and can then be painted over with another shade of Octopus Write & Draw ink or watercolour. It is eraser-proof and most of the colours are also highlighter-proof.
Both pure and diluted with water, Octopus Write & Draw ink is excellent for colouring. Used undiluted, the waterproof ink convinces with its opacity. The many colours of Octopus drawing ink can be mixed with each other, but also with water. In this way, countless colour shades can be achieved for beautiful watercolour effects.
Unlike most other waterproof inks, Octopus Write & Draw can be used in a fountain pen without hesitation. However, care should be taken not to let the fountain pen dry out. We therefore recommend that you rinse and clean your writing instrument carefully after use to prevent the ink from drying up accidentally.
The Octopus special cleaner for pigmented inks is available for cleaning your writing Instruments.
