Operations

The following operations are currently available with Saddler version 0.5. Please see our Templates for examples of these operations in use or let us know if you need an operation not listed.

Laser Cutting

Laser Cutting

Cut Example

Design Style: Red Stroke (HEX: #FF0000, RGB: 255 0 0)

Description: Laser beam cuts through material, following paths like a pen drawing a line. Cut edges will be dark brown or black. Edge Burnishing operation can remove this appearance.

Special Considerations: The smooth or “grain” side of the leather is always facing up in the design file. Asymmetrical parts that are sandwiched together smooth sides out should be mirror images of their mating part.

Laser Skiving

Laser Skive

Design Style: Purple (#800080) Gradient

Description: Laser beam makes a partial thickness etch on the back or “suede” side of leather to reduce bulk on stacked or folded sections.

Special Considerations: Skiving reduces leather thickness by approximately 2/3 at 100% gradient density, tapering to 0 reduction at 0% gradient density.

Vector Etching

Vector Etching

Design Style: Blue (#0000FF) Stroke

Description: Laser beam makes a partial thickness etch in material, following paths like a pen drawing a line. Initial black mark will lighten over time, but remain permanently.

Special Considerations: Marks designed to go completely to the edge of a design (full bleed) should continue past adjacent cut lines.

Raster Etching

Raster Etch

Design Style: Black (#000000) Fill

Description: Laser beam makes a partial thickness etch in material, marking a filled area by moving back and forth like the head of digital printer. Initial black mark will lighten over time, but remain permanently.

Special Considerations: Marks designed to go completely to the edge of a design (full bleed) should continue past adjacent cut lines.

Wet Stamping

Wet Stamp

Design Style: Green (#008000) Fill

Description: An acetal stamp is made and pressed into wetted material, leaving a permanent debossed mark.

Special Considerations: Image will appear on final product in the same orientation as in design file; it does not need to be reversed in the file. Marks designed to go completely to the edge of a design (full bleed) should continue past adjacent cut lines.

Assembly Folding

Fold

Design Style: Teal (#008080) Dashed Stroke

Description: A fold required for the assembly process before additional steps (such as stitching or riveting) can be performed.

Special Considerations: This is a no-charge operation. Folds that can be made after assembly is complete (the fold in a bi-fold wallet, for instance) should not be marked in this way.

Assembly Reference Numbers

Assembly Reference

Design Style: Teal (#008080) Fill Text

Description: Identifies parts and sub-assemblies within a design file.

Special Considerations: Each part in a design file should be, at a minimum, labeled with a unique Assembly Reference ID starting with the number 1. Subassemblies (if applicable) should also be grouped with the addition of a letter following the number. Additional assembly instructions, if required, are collected in a form outside of the design file.

Cementing

Cement

Design Style: Yellow (#FFFF00) Fill

Description: A flexible, permanent leather cement is applied to the fill area on the back or suede side of the leather to laminate two layers of leather together.

Special Considerations: Both mating surfaces should be marked for leather cementing. Bond strength tends to exceed that of material, but stressed areas should still be reinforced with Hand Stitching.

Component Application

Component

Component

Design Style: Teal (#008080) Fill (Component Outline), Red (#FF0000) Stroke (Component Through-hole, if applicable)

Description: Marks the placement of any type of hardware or other non-leather component within a design.

Special Considerations: A no-charge solid Teal shape (Component Outline) with matching size, shape, and position of the component it is representing should be included in the design file. Any hole required to place a component in the design (Component Through-hole) should be marked as other Laser Cutting lines in Red. The number and type of components added is collected for quoting in a form outside of the design file.

Lockstitching

Lockstitch

Design Style: Lime (#00FF00) Stroke (Primary Placement), Teal (#008080) Stroke (Stacked Placements)

Description: A durable machine stitch made to join stacked or overlapping material.

Special Considerations: When a single lockstitching seam appears on multiple stacked parts or overlapping layers, only the longest continuous location of the seam (Primary Placement) should be marked with a Lime-colored stroke. Additional locations that will be joined with the same seam (Stacked Placements) should be marked with a no-charge Teal stroke to indicate alignment.

Hand Stitching

hand stitching

Design Style: Red (#FF0000) Stroke (Stitching Holes), Teal (#008080) Stroke (Stitching Paths)

Description: The following hand stitching types are currently available:

Double Wrap Stitching: A double stitch wrapping around the edge of two or more stacked pieces. Often used for retaining strap ends or components. This is the only stitch performed after Edge Burnishing (if applicable).

Special Considerations: Stitching Holes should be marked as other Laser Cutting lines in Red. The location of the stitches themselves (Stitching Paths) should be marked in no-charge Teal. The number and type of hand stitches is collected for quoting in a form outside of the design file.

Edge Burnishing

Burnish

Design Style: Olive (#808000) Stroke

Description: After assembly, exterior leather edges are sanded, have a gum-based finished applied and are polished against a rotating wooden drum. The resulting finish is smooth and slightly darker than the base leather color.

Special Considerations: Edge Burnishing should be marked at a visible outset from the part edges to which it will be applied. If multiple stacked parts share an edge after assembly, only the part with the longest external edge should be marked. Only edges that are on the exterior of a completed assembly (with one Hand Stitching exclusion, see below) can be burnished.
