Cheyenne Safety Cartridge Needle SHADER (RS)

Cartridge needles With the Safety cartridges, Cheyenne proves once again its leader in innovation, they represent a milestone in work safety, simplicity and hygiene. The needles come with a patented safety membrane that prevents blood and ink from entering the handle. The tightness of the membrane complies with the requirements of the European standard EN 17169. Experienced experts make sure that the needles are in compliance with medical standards (ISO 13485)Material: Stainless steel The needles are single-use and sterile packaged The price is per piece Cheyenne Safety SHADER (RS) is the flagship round shader of the Safety range, delivering precision shading and pepper shading at the highest level of conventional membrane cartridges. The advanced Safety membrane ensures constant ink flow and complete anti-backflow protection, ideal for shading techniques requiring absolute control. The RS configuration arranges needles circularly with optimized spacing for controlled ink deposition in small and medium areas. Made in Germany, premium surgical steel, microscopic polishing, #12 gauge (0.35mm), medium taper. Gamma sterilization. Universal compatibility with all pen-style machines. Available from 3RS through 14RS — one of the most complete RS ranges in the industry. Compared to Kwadron RS, Safety wins on ink flow and consistency. Against Craft RS, Safety brings an advanced membrane with perceptible difference. Against Capillary RS, Safety is 20-30% more accessible, good enough for 90% of applications. Box of 20 cartridges, CE. The daily choice of professionals for fine shading, pepper shading, texturing, and blending in tight areas. Complementary to Safety RL for lining and Safety RM/M1 for large surfaces. Frequently Asked Questions What makes Cheyenne Safety RS superior to other RS? The advanced Safety membrane offers the most consistent conventional ink flow in the industry, critical for RS where deposition control makes the difference between mediocre and exceptional shading. German manufacturing with individual inspection ensures every cartridge feels identical. Microscopic needle polishing minimizes trauma. Gamma sterilization eliminates chemical residues. The combination of these factors creates an RS that functions predictably and impeccably, hour after hour. What Safety RS configurations are available? Cheyenne Safety RS offers a complete range: 3RS, 5RS, 7RS, 9RS, 11RS, and 14RS. 3RS: micro-texturing, ultra-fine details. 5RS: most popular, versatile shading. 7RS: medium areas, neo-traditional shading. 9RS: medium-large areas. 11RS: round shading on larger surfaces. 14RS: nearly the size of a small magnum. All in #12 gauge. Recommended stock: 5RS (50%), 7RS (30%), 3RS (20%). What voltage for Safety RS? Optimal voltage: 6-8V. Fine pepper shading 3RS: 5.5-7V. Standard shading 5RS-7RS: 7-7.5V. Dense shading 9RS+: 7.5-8V. Safety RS has a wide sweet spot thanks to the advanced membrane. Golden rule: if you see visible individual dots instead of homogeneous shading, either voltage is too low or movement is too fast. Build tone progressively with multiple light passes. Is Safety RS good for B&G portraits? Excellent. Safety RS is indispensable for B&G portraits — 3RS for skin texture, pores, and eyelashes; 5RS for base tones and subtle transitions; 7RS for main shadows. Combined with Safety RM for larger areas, RS+RM covers 100% of a portrait's needs. Use pre-mixed grey washes with Safety RS at 6-7.5V for progressive tone building with maximum depth. How does Safety RS compare to Capillary RS? Safety RS offers 90% of Capillary RS performance at 70% of the price. Capillary wins with capillary flow that is more constant over long sessions (5+ hours) and ultra-fine techniques (single-dot pepper shading). Safety wins on accessibility and is more than sufficient for standard sessions (2-4 hours). Practical recommendation: Safety RS for daily use, Capillary RS only for special realism projects where every nuance matters most. Does Safety RS work with diluted ink? Yes, Safety RS works well with diluted ink for grey washes. The Safety membrane handles medium-thin consistency inks well. Optimal dilution ratios: 1:1 (medium grey), 1:2 (light grey), 1:3 (very light grey). At extreme dilutions (1:4+), flow may become excessive — use lower voltage and faster movements to compensate. Witch hazel is the recommended dilution solvent. How many RS Safety cartridges for a session? For a 2-4 hour shading session with RS Safety, prepare 4-8 cartridges. RS wears faster than M1/RM — each needle bears more wear on an RS with fewer needles. Change cartridge every 25-40 minutes of active work. For complex portraits (4-6 hours of shading), prepare 8-12 RS cartridges in a size mix. Never continue with dull needles — quality degrades and trauma increases. Is Safety RS compatible with Bishop Fantom? Yes, works perfectly on Bishop Fantom. Optimal voltage on Fantom: 6.5-8V. Fantom's 3.0mm stroke is ideal for RS — provides sufficient travel for controlled shading without excessive penetration. The Fantom + Safety RS combination is one of the most popular in the industry for realism and semi-realism. Fantom's powerful motor efficiently drives all RS configurations, from 3RS to 14RS. Can Safety RS be used for soft lining? Like any RS, Safety RS can create soft/blurred lines on small configurations (3RS, 5RS), but it is not the equivalent of an RL. Result: a soft, slightly blurred line with distinct artistic character. Suitable for watercolor, illustrative soft, and sketch tattoo styles. For conventional lining with clear edges, use Safety RL. Some artists intentionally use 3RS Safety for a 'pencil-drawn' outline look highly valued in certain contemporary styles. What warranty does Cheyenne offer on Safety RS? Cheyenne guarantees sterility and compliance of each Safety RS as long as packaging is intact and expiration date not passed. Manufacturing defects (bent needles, defective membrane) — contact distributor with lot number for replacement. Defect rate: below 0.1%. Never use a suspect cartridge — report and obtain replacement. Cheyenne has the strictest QC in the industry.
