In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.

The present invention relates to a platform that may be utilised in the field of biosensors. According to the present invention there is a method of manufacturing a platform for use in bio-sensing applications comprising the steps of: a) providing a substrate having electrodes thereon; b) performing an overprinting step by overprinting the electrodes with a precursor solution; c) performing a drying step to dry the precursor solution to form a print layer on the electrodes; d) performing a further overprinting step by overprinting the print layer with a precursor solution to increase the print layer thickness; e) performing a transformation step to at least partially transform the print layer from a first substance to a second substance different to the first substance.

A halftone raster image, suitable for rendering a continuous-tone image, which comprises a plurality of dots, arranged according a screen ruling and screen angle. Said dots comprise (i) image pixels arranged as a first arc or as a plurality of arcs which together represent a first spiral, and (ii) non-image pixels arranged as a second arc or as a plurality of arcs which together represent a second spiral. Small displacements of the feed point of said dots away from the theoretical centre of a halftone dot, defined by said screen ruling and screen angle, enable a higher image quality and less patterns in said halftone raster image.
