KOH-I-NOOR Kalka maszynowa A4 25 sheets (238850) carbon paper for typewriters and duplicating

KOH-I-NOOR Kalka maszynowa A4 25 sheets (238850) carbon paper for typewriters and duplicating is a pack of thin, single-sided transfer sheets in standard A4 format. Designed to produce immediate copies from typewriters, adding machines, cash registers or for manual tracing, these coated sheets transfer ink reliably onto a copy sheet placed beneath the original. The slim profile preserves stack height and fits standard A4 paper handling for office or field use.

Advantages

The carbon sheets are single-sided coated to provide consistent, legible copies without smudging on the blank side, and their A4 size matches common document formats. The lightweight, thin construction allows multiple sheets to be used without significantly increasing paper thickness, and the pack of 25 sheets offers a compact supply suitable for occasional to moderate copying needs. Coating formulation and sheet finish deliver predictable transfer quality with standard mechanical or manual input.

Suitable for

• Making immediate copies from typewriters
• Creating duplicates with mechanical adding machines and cash registers
• Manual tracing and pattern transfer
• Office, accounting and administrative paperwork requiring instant copies

Key specifications

• Format: A4 (210 × 297 mm)
• Quantity: 25 sheets per pack
• Coating: single-sided transfer coating
• Sheet construction: thin, lightweight transfer paper
• Compatibility: suitable for typewriters, adding machines and manual tracing

How to use

Place the coated side of the carbon sheet facing downwards underneath the original document and above the copy sheet. Operate the typewriter, register or tracing tool over the original document; applied pressure transfers the coating to the sheet below to form a copy. For best results use clean, flat paper stacks and apply steady, even pressure. Replace sheets after each use or when transfer intensity diminishes.

Usage recommendations

Store the pack flat in a dry, cool place away from direct sunlight and humidity. Keep coated side covered to avoid accidental marking. For sustained copy quality, use with standard-weight A4 copy paper and avoid excessive pressure that could emboss or tear thin sheets.
