Artists employ various techniques to create sketches and designs for gold coins or medals, adapting traditional methods or utilizing digital tools for visualizationHand-Drawn Sketches
Sketches using pen or pencilMost artists start with sketching their ideas on paper using pens or pencils. These initial sketches can assist you in conceptualizing and planning the layout and style of your coin or medal.
Detail Rendering. The artist improves their initial sketches. They include more details and contours the sketch, aswell in fine-tuning the composition. This process can require multiple variations.
Inking or Tracing- Once satisfied with the sketch in pencil then the artist can draw the design in a way to create a clearer and more precise outline. Tracing the pencil sketch on a fresh sheet or tracing paper is common for this step.
Include Depth and Shade Artists can use shading techniques to create depth and dimension in the design. This gives the design a more authentic appearance or emphasize specific elements of the design.
Digital Design Creation
Graphic Design Software- Artists proficient in digital design use programs like Adobe Illustrator, Photoshop, or specialized 3D modeling programs. They design the coin or medal design digitally, utilizing tools to ensure precision, scale, and manipulation.
Vector GraphicsDigital design typically created by using vector graphics. Scalability can be achieved without sacrificing quality. This permits the design's changing size to accommodate different sizes of coins.
3D Modelling: Artists who are skilled can use 3D modelling software to visualize coin or medal designs in a 3-D environment. This provides a more precise illustration of the final design, and lets you better comprehend how it will look.
Visualization: Artists are able to render their digital designs in order to create a simulation of what a coin or medal will appear like when they are finished. They can apply a variety of designs, effects or even textures.
The use of digital or hand-drawn methods requires the greatest attention to the specifics, artistic talents as well as an understanding and appreciation of technical limitations. Artists are able to choose which method they prefer based on their personal knowledge, their requirements for customers, or the aesthetics desired for the final product.

How Can The Janvier Machine Transfer A Gold Coin Or Medal Design To The Working Hub Of The Master?
The Janvier machine (also called pantographs or reducing machines) is a specific device that transfers an image of a coin or medal from the master hub to the working hub. The Master Hub Creation is explained in this video.
The master hub is the original die, or mold, which contains the exact layout for the medal or coin. The master hub is generally manufactured with CNC methods of machining or other methods of precision to ensure precision.
Janvier Machine Installation
The Janvier Machine is comprised of two parts: a stylus to trace the design, and a tool which cuts the design.
The Janvier machine is equipped with an incredibly secure master hub. This is used as a template to where the design is transferred.
Finding the Design
The stylus on the Janvier machine is able to follow the contours and specifics of the design that is on the hub master. As the stylus moves across the surface of the master hub it tracks the design's shape.
The DesignReducing the Design
The Janvier machine also duplicates the pattern that was traced on the working hub. This hub is typically made from a softer material like steel or nickel, than the hub used in the master.
The cutting tool cuts, or duplicates the design on the hub of work at a reduced or smaller dimension compared to the hub that is master. This reduction is crucial for the process of minting, since it allows for the striking of coins or medals at the exact size.
Precision and Accuracy-
Janvier machines are controlled with a high degree of precision to ensure the exact transfer of design from master hub to working hub. It faithfully recreates the tiny details and contours.
Quality Control
The hub that is used for the operation will undergo inspection and quality control to ensure it meets the specifications and is accurate for the striking procedure.
More Processing
The Janvier working hub is an instrument to facilitate the process of striking coins or medals. The die or mold is used to make numerous coin blanks or medal blanks by using the transfer design.
The Janvier machine's role is crucial for the minting process it allows the replication and reduction of complex medal or coin designs from a master hub to working hubs precisely. The working hubs can be used to create mass production of coins and other medals using the strike process.
