Dip pen nibs for writing
An overfeed is a tool that shines over a dip pen nib and provides extra useful functions towards drawing or writing. Overfeeds are specifically of use with flexible dip pen nibs, because their functions offer the benefit of flex.
Note: at the moment, overfeeds are given on our Pump Pens only. Develop to make them on our Fountain Pens shortly. This informative article is a companion of article making use of Overfeeds.
Overfeeds are believed old-fashioned products, although 1 or 2 modern-day makers of ink pencils for attracting provide them with their nibs.
An overfeed gets its title from fact that it sits throughout the nib and feeds ink toward plunge pen nib. The underfeed is the standard feed underneath the nib found on many fountain pens. The underfeed is given ink directly from the reservoir inside pen. The overfeed is given ink ultimately as ink migrates into the area involving the nib while the overfeed.
Overfeeds were very popular when versatile plunge nibs had been a favorite writing and attracting unit. Overfeeds are made exclusively for flexible dip pen nibs, and enable you to draw with a wider variation inside range width. A well-handled versatile nib are able to turn a 2D drawing into a 3D knowledge by subtly altering the range width.
That's what you want whenever you draw with a flexible the nib: variation inside line width, from slim to dense and back. The worthiness of an overfeed is based on the ratio of your slim to thick lines. A flexible plunge pen nib that typically draws what is known as a “hairline” can, when flexed, increase the width associated with attracted range 4 or 5 fold. That is a 5:1 proportion. The same plunge pen nib with a well-matched overfeed can double the proportion. For example, the Manga G plunge pen nib with your overfeed provides a line variation of almost 10:1, as shown below.
That's the hairline from the right and a much wider line regarding the left allowed because of the overfeed.
It’s crucial that you note that you are able to encounter several dilemmas whenever using versatile plunge pen nibs. Overfeeds provide methods to those issues.
Initial problem takes place when the nib flexes backwards. The circulation of ink through the underfeed towards the nib stops, so does your drawing or writing. A well-designed overfeed keeps feeding ink into the nib after it offers bent backwards in order to continue drawing or writing. The overfeed never ever loses connection with the nib as it bends backwards with all the nib.
The second issue does occur since the two tines associated with the flexing plunge pen nib spread outwards. Capillary action encourages ink to flow along the ink station within the nib, and surface stress works to keep consitently the ink moving in a continuing range it doesn't break. As a dip pen nib flexes and also the tynes individual, both forces are quickly overcome because of the split, additionally the ink line breaks. Once again, the overfeed if properly designed solves the situation. The end of the overfeed slips between the 2 tines and bridges the space among them. This provides a bridge when it comes to flow of ink and lets you continue attracting even though the plunge pen nib flexes upwards and outwards.
