Bead: A concave (interior bead) or convex (exterior bead) area, typically 1/8” wide, spanning the circumference of the tin to enhance its strength and stability.
Body: Refers to a can without a lid; the base of a container.
Cover: The lid or closure of a can.
Curl: A section of tin folded inward to create a safe, rounded edge.
Distortion Printing: A printing technique used for seamless tins, where artwork is intentionally distorted to fit onto flat metal and then adjusted as the tin is formed.
Dome: A type of cover with a flat horizontal surface (top) that smoothly transitions into a vertical skirt.
Drawn Can: Also known as a seamless tin, formed from a single piece of tin drawn to create the container.
End: The bottom area of a tin, which can be attached by seaming or crimping.
Four-Colour Process: A printing method utilizsing cyan, magenta, yellow, and black to produce a wide range of colours.
Full Friction: A closure where a plug-style metal cap fits tightly inside the can.Hem: Similar to a curl, an area of tin folded inward to create a safe, flattened edge.
Interior Seal: A closure option where a pliable ring fits inside the tin, allowing for a slender profile can.
Layout: A two-dimensional drawing depicting the specifications of a tin in its flat state, used for designing artwork.
Lithography: A printing method on flat metal sheets later formed into tin cans.
Lock-Seam: Side walls of the tin attach by hooking onto each other, often used for decorative tins.
Multiple Friction: A closure where a plug fits into a ring, creating multiple sealing surfaces.
PMS: The Pantone Matching System, used for spot colours.
Pre-press: Preparation of artwork before printing.
Radius: The curved area of an off-round tin or cover.
Seamless Tin: A tin made from a single piece of drawn tin.
Single Friction: A closure where a plug-style cap fits into a seamed-on ring, creating one sealing surface.
Slipcover: A closure where the cover's skirt slips over and outside the can body.
Stepped Cover: A slipcover design with a step between the horizontal and vertical surfaces, facilitating stacking.
Varnish: A protective coating applied to the metal, available in gloss, matte, and stipple finishes.
Welded Seam: Side walls attach through heat, forming a tin body.
White Coat: The entire metal surface coated with white before printing.
