Flow Carts Red Label RS Round Shader Tattoo Cartridge Needles
The Flow Carts Red Label RS Round Shader is designed for tattoo artists who need controlled shading, colour application and versatile needle performance.
RS stands for Round Shader. The needles are arranged in a round configuration, making this cartridge useful for shading, colour packing and working into smaller areas where a larger Magnum configuration may not be suitable.
Red Label RS cartridges can be used across a wide range of tattoo styles, including traditional, black and grey, colour, illustrative and detailed tattoo work.
Designed for Shading and Colour
Round Shader cartridges are commonly used for:
Soft shading
Controlled shading
Colour packing
Small areas of colour
Blending
Traditional tattooing
Black and grey
Illustrative tattooing
Small detail work
Filling smaller areas
The final result depends on the complete tattooing setup. Machine type, voltage, hand speed, needle depth, ink, skin and individual technique all affect the finished tattoo.
What Does RS Mean?
RS means Round Shader.
Round Shader cartridges use needles arranged in a round configuration.
Compared with a Round Liner, an RS configuration has a more open needle arrangement, making it useful for depositing and spreading ink over an area rather than concentrating entirely on a single defined line.
This makes RS cartridges a versatile option for artists who need both shading and controlled colour application.
RS for Different Tattoo Styles
Traditional Tattooing
Round Shaders are commonly used for shading traditional designs and filling smaller areas of colour.
Black and Grey
RS cartridges can be useful for controlled shading and building darker areas without immediately moving to a larger Magnum configuration.
Colour Tattooing
Round Shaders can be used for packing colour into smaller areas and working around detailed parts of a design.
Illustrative Tattooing
RS cartridges can provide controlled shading and colour application within detailed illustrative work.
Small Areas
The round configuration can be useful when working in smaller areas where a larger shader or Magnum would be less practical.
Controlled Shading
Round Shader cartridges provide a useful middle ground between linework and larger shading configurations.
They can be selected when you need more coverage than a Round Liner but still want a relatively compact needle grouping for controlled work.
Different RS groupings can be selected according to the size of the area, desired shading effect and individual tattooing technique.
