SuperPNG is an open source Adobe Photoshop plug-in for using PNG ("ping") files. It has more comprehensive support for the format than Photoshop's included plug-in and provides control over alpha channel handling. It includes some additional options for saving PNGs: Alpha channel control, Variable Compression, Smart Quantization, ICC profile embedding and Meta Data saving.
With this plug-in you can customize printing with imagePROGRAF series.
