Go to close with the press to zero load, making sure that the press closes evenly. * machine production * machine speed required * basis weight calculation * head level requirement * spouting velocity * head box flow rate * efflex ratio *. Sandwich the transfer and developer sheets together with the matte sides contacting each.
