Tracing paper is paper made to have low opacity, allowing light to pass through. Its origins date back to at least the 1300s, when it was used by artists of the Italian Renaissance. In the 1880s, tracing paper was produced en masse, used by architects, design engineers, and artists. Tracing paper was key in creating drawings that could be copied precisely using the diazo copy process. It then found many other uses. The original use for drawing and tracing was largely superseded by technologies that do not require diazo copying or manual copying (by tracing) of drawings. The transparency of tracing paper is achieved by careful selection of the raw materials and the process used to create transparency. Cellulose fibre forms the basis of the paper, usually from wood species but also from cotton fibre. Often, paper contains other filler materials to enhance opacity and print quality. For tracing or translucent paper, it is necessary to remove any material which obstructs the transmission of light.How is paper made translucent (grease proof, tracing paper)?

and hydrolysing them by very prolonged beating in water. There are three main processes to manufacture this type of paper, as follows: # Through mechanical 'refining' of the cellulose fibre to create a fibre which is highly fibrillated and gelatinous, so that in forming the sheet of paper, virtually all air is excluded from the internal structure of the paper. This method produces a very translucent and even looking paper over a range of areal densities from 42 to over 280 g/m². # By making a 'normal' sheet of paper and then filling the spaces between the fibres with a material that has the same refractive index as the cellulose. This was a common process adopted in the USA. The product was frequently called Vellum, although this terminology can refer to a wider range of special papers. Due to the relatively high cost, this method of manufacture has largely disappeared. # As with 2, by making a normal sheet of paper, which is followed by immersing uncut and unloaded paper of good
